this option causes window activation requests to only activate a window if it is on a currently visible virtual desktop, otherwise it will be set as urgent. I recall that things may have worked this way long ago...
the main idea here is to not DRAW at the time of the first damage to avoid overdraw, but ignoring the fact that the region is ready to be drawn can be problematic when the drawing eventually occurs. best choice here is to keep the region but not the render update
reshadowing earlier than this makes it very likely that client attributes have not been fetched, meaning that the match will fall through to a default type match instead of using the correct one
it seems i have an override-redirect window just off the bottom-right
of my screen - i think its the scim input panel status. what happens
is it is "managed" by comp but then deleted (_e_comp_x_hook_client_del
called), BUT _e_comp_x_object_add is called with a deferred event for
that client to add it again (likely this is a race) which finds he
client in a state of not having comp_data as the E_FREE in
_e_comp_x_hook_client_del() frees it and sets it to NULL. move the
comp_data free to the actual client free (which is the last time a
client is valid at all) solves this.
instead of adding specific handling which will work (sometimes) in one specific case, expand already-existing api to provide the needed functionality for iconify animations. now on emitting any signal to a comp object, optional glob-able effect providers can be hooked and prioritized to add effect animations
also use animating flags now when applying an object effect
a base effect is provided in elementary, but now each module which wants to hook iconify animations (or other events) can do so in the theme and have different animations with their module
ibox now uses this as an initial test. there are teething problems:
1. unknown location for new icon (guess that its on right)
2. stacking - the animation is at the stacking layer of the comp obj
... this probably needs a way for the comp shobj to request a
temporary stacking change until anim done
this fixes a race condition when windows open simultaneously and then are stacked under each other: the previous result was that they would end up hanging out at the top of the window stack (above all windows) until another window was raised above them. now they stack as expected
this was pretty old/legacy and looked like it would fall over pretty easily. there's no users and I see no use for it, so it goes bye bye
removals: e_main_idler_before* api
previously there were cases where client focus was not explicitly unset on delete, which resulted in expected client hooks not being called and minor inconveniences to occur
this flag is used to block most cwm actions until after the client is past its first loop iteration. overrides, however, don't need to be blocked and will in fact break sometimes (fuck you gtk) as a result
it's worth noting that showing/hiding overrides extremely fast will still break the compositor a little in that I'm not going to render a single frame while constantly playing edje hide/show animations which are longer than the actual render. with animations disabled, however, rendering occurs as expected.

so comp would call ecore_x_composite_window_events_enable in
_e_comp_x_client_shape_input_rectangle_set()
_e_comp_x_hook_client_post_new_client() all the time.. because
ec->need_shape_merge was always set.. why was it always set.. because
ecore_x_composite_window_events_enable woudl set shape rectangles to
make the window visible to input events... so e would feed itsefl with
events all day long via x. this shortcuts that to check if event rects
are the SAME then don't set them as the ones that are stored.
we can assume that these are always going to be ready for drawing immediately, and sometimes X fucks up the damages so it's best to go with the full frame from the beginning
there's an event from ecore-x which tells us when this property has changed, which means we no longer have to be constantly checking to see if other apps have changed it
when not dealing with a re_manage client (persisting from previous E instance), we're almost definitely going to get multiple full-window damages as a new client starts up. the first damage USUALLY results in a garbage render, so ignoring it makes the first frame become actual window content (good!) or a transparent rect until the client finishes drawing (not good!), which is at least an improvement over showing random pixels
this is what I'll be using to conceal various features in the future which should not be used without some understanding of what they do (OR FACE THE CONSEQUENCES)
xorg 1.15 introduces this extension which has a magical event to notify when a pixmap's size changes, which means that the size never needs to be manually fetched
this option provides the functionality which was intended by the old and broken "raise on focus" option. it raises windows ONLY when reverting focus in cases not directly triggered by the user or any application
after this commit, the new-but-invisible module "lokker" (or other custom loaded module) is in charge of creating all graphics for the lock screen, and it will be added to the user's config. failure to load a lockscreen module will just result in a black screen
desklock subsystem now handles all the pre/post lock stuff while the modules themselves are responsible for creating visuals and calling auth functions to determine whether to unlock the screen
if we're running in a non-X environment, we can't very well expect that using X calls to hide/show windows for desklock is going to work as expected. now a compositor backend can add a pre or post desklock hook to hide/show its clients as necessary
if a client's X attributes fail to be fetched on the first attempt, it's possible that we might succeed on a second attempt, which would prevent us from losing a client
in some cases, it may be desirable to block shape cutting for an amount of time to reduce cpu calculations. this should be set when performing any non-interactive compositor effects
this flag allows a client's layer to be changed instantly with no protocol-level checks or work, allowing compositor effects to do their work more easily
the existing moveresize popup infrastructure is very limiting in that it requires you to create a popup. if you don't want to create a popup, now you don't have to.
p16 is a pager replacement module which uses deskmirror to show you live views of each desktop. it has a separate theme and reuses a lot of pager code.
not sure if original pager should be kept, but it's still around for now.
pager and pager16 both provide the same gadget and cannot be loaded simultaneously
* finish updating for E19 api
* fix visibility changing on sources
** use that shelf data item added in previous commit to detect shelf visibility
* fix sizing (but not scaling :() and positioning of sources
* also fix stacking
pointers in E now come in two flavors, one for each protocol that we currently support. each is created from the owner compositor backend:
X pointers still work as usual
Wayland pointers are actually surfaces that we dump image data into periodically to render them as evas images
some small amounts of hack is necessary to make this work, namely blocking X pointers when a Wayland one is in use if we're running a multi-protocol compositor
variable takes the name of the output module s/wl_// ; example: E_WL_FORCE=x11
this module allows easy loading of a wayland output module to override any detection which may occur by force-loading the module during startup
in a later commit, an actual output detection mechanism needs to be added to run through all the possible output modes
this is the first of the wayland output modules, and it is extremely simple as a result of the compositor rewrite. for any other wayland output modules, it should be enough to simply create an ecore_evas canvas and do startup in this way.
* try to clear up build system for separating out ecore-x
* add #ifdefs for lots of ecore-x stuff
* break out some internal e wl functions for reuse in api
* store wl surface buffers as an inlist
* add protocol-specific client compositor data
** move lots of X client attributes here
* add pixmap type checks to a number of X-specific things, such as grabinput, to block them for non-X clients
* rearrange startup order to work with wayland
* move X screensaver code to e_comp_x
* flag modules still requiring X with -DNEED_X
given that compositing is always enabled and that it's crucial to be able to change these settings, potentially having them unavailable is not a great way to live
huge fustercluck commit because there wasn't really a way to separate out the changes. better to just rip it all out at once.
* compositor and window management completely rewritten. this was the goal for E19, but it pretty much required everything existing to be scrapped since it wasn't optimized, streamlined, or sensible. now instead of having the compositor strapped to the window manager like an outboard motor, it's housed more like an automobile engine.
** various comp structs have been merged into other places (eg. E_Comp_Zone is now just part of E_Zone where applicable), leading to a large deduplication of attributes
** awful E_Comp_Win is totally dead, having been replaced with e_comp_object smart objects which work just like normal canvas objects
** protocol-specific window management and compositor functionality is now kept exclusively in backend files
** e_pixmap api provides generic client finding and rendering api
** screen/xinerama screens are now provided directly by compositor on startup and re-set on change
** e_comp_render_update finally replaced with eina_tiler
** wayland compositor no longer creates X windows
** compositor e_layout removed entirely
* e_container is gone. this was made unnecessary in E18, but I kept it to avoid having too much code churn in one release. its sole purpose was to catch some events and handle window stacking, both of which are now just done by the compositor infra
* e_manager is just for screensaver and keybind stuff now, possibly remove later?
* e_border is gone along with a lot of its api. e_client has replaced it, and e_client has been rewritten completely; some parts may be similar, but the design now relies upon having a functional compositor
** window configuration/focus functions are all removed. all windows are now managed solely with evas_object_X functions on the "frame" member of a client, just as any other canvas object can be managed.
*** do NOT set interceptors on a client's comp_object. seriously.
* startup order rewritten: compositor now starts much earlier, other things just use attrs and members of the compositor
* ecore_x_pointer_xy_get usage replaced with ecore_evas_pointer_xy_get
* e_popup is totally gone, existing usage replaced by e_comp_object_util_add where applicable, otherwise just placed normally on the canvas
* deskmirror is (more) broken for now
* illume is totally fucked
* Ecore_X_Window replaced with Ecore_Window in most cases
* edge binding XWindows replaced with regular canvas objects
* some E_Win functionality has changed such that delete callbacks are now correctly called in ALL cases. various dialogs have been updated to not crash as a result
