many times it's useful to have an event for actual zone geometry change
vs useful geomtry change, so split this out and use the right handler where appropriate
so we cast a lot of ptrs to other types as that is then the actual
type of the object. all these objects are allocated by malloc nad
friends so this is ok. but gcc on arm is not happy and warns. maybe it
assume this ptr could be to an element in an array of structs of this
type and so on thus will have specific alignment enforced by compiler
but our casting may disturb it? anyway. cast via void first fixes it.
we can focus on other real warnings and errors instead.
So yeah, I've literally used sed to replace every occurrence of
ecore_time_add() with ecore_timer_loop_add() because I'm reasonably
confident that no part of E has a legitimate need for timer based on the
exact current time.
It would be really nice if I'm not wrong. :)
The reason for this is the incredible spew of clock_gettime() calls I'm
seeing on an ARM system (that should have a vdso for gettime, but...)
This can amount to thousands of system calls per second.

in many cases where a zone's useful geometry is marked dirty, the resulting
recalc ends up having the same useful geometry as before: this is the case
for things like tasks gadgets, which continually expand and contract along
a single axis and thus will never affect useful geometry while still forcing
a recalc
by ignoring these cases, a huge amount of compositor thrashing is avoided and
a number of related bugs can also be fixed
I added a lower quality and less precise workaround for this before
since I didn't have enough test cases to think of something which would
be suffiently good to handle all cases.
as a result, initial calculations for obstacles would incorrectly detect
horizontally-oriented obstacles as being vertical, causing inconsistencies
in window placement. this would become even more severe if the obstacle
never resized itself, erroneously modifying window placement to position
around obstacles which did not exist
having a hint on the obstacle to indicate a direction is sufficient for
most cases, specifically zone useful geometry calcs, where obstacles are
expanded to cover the entire screen on which they reside and must expand
accurately based on the orientation of the obstacle
ref 10c43efc83
this fixes an issue where shrinking vertical shelves would cause vertically
maximized windows to always match the height of the shelf
possibly needs improving later depending on usage of zone obstacles in
the future...
these are generic objects which can be added to indicate that there
is something blocking window placement at the edge of a screen/desk.
this replaces the traditional method of watching shelves to calculate
useful geometry with a managed object which will automatically trigger
a recalc whenever it is updated, and it allows non-shelf objects to
more easily register themselves as obstacles for window placement
so e has a bit of a problem. we mostly deal with zones, BUt these
zones come from our old xinerama code (this likely should just die
some time) and THIS code gets fed info from e's randr code. we
re-fill/modify as randr finds new screens or things get reconfigured.
thus zones adapt. the problem is now all our zone code really has a
hard time reverse mapping the zone back to where it came from -eg the
randr screen data. you literally can't do a whole bunch of things like
know if that zone was an internal laptop lid or an external screen, or
if it was rotated or even what the dpi is... as you ave no deasy way
to map it back other than by guessing geometry matches.
this fixes that by storing the randr screen id (which should be
unique) fromt he original src randr screen in the xinerama screen and
then in the zone. with this you can do a quick lookup in the e randr
data should you ever need to find the info. this should pave the way
for some other fixes/improvements, but without this they cannot be done.
@fix
as a result of earlier changes which prevented recursive desk flips,
e_desk_show() now rejects some desk show calls which are invalid such as
a show where the "current" desk does not have the visible flag set. this
behavior is overridden in the case of startup, which is functionally the
same effect as changing the desk count
fix T2717
this makes highest priority screen the lowest (0) zone. this also
handles missing screesn that you are relative "of". missing clones are
not working atm. also zone reconfigure moves windows now too
there is only one E_Comp which can now be accessed by the e_comp global.
if you're editing a file with some uses of these deprecated functions, replace their usages with appropriate references to this variable
pass -Wno-deprecated-declarations to ignore these warnings during build
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
comp files and descriptions:
e_comp.c - overall compositor functions, rendering/update loop, shape cutting
e_comp_x.c - X window management and compositor functionality
e_comp_wl.c - Wayland surface management and compositor functionality
e_comp_canvas.c - general compositor canvas functions and utilities
e_comp_object.c - E_Client->frame member for managing clients as Evas_Objects, utility functions for adding objects to the compositor rendering systems
additional authors: ivan.briano@intel.com
feature: new compositor
removal: e_border, e_container, e_popup
* remove xwin for container canvas: now drawn directly on the compositor canvas
* added SHAPE_DEBUG define for bored developers
* bindings now use new e struct for mouse/wheel events
* container+zone now get mouse events from smart callbacks instead of x events
* rename comp api namespace
* change comp underlay theme to have a swallow for the wallpaper
* add names to all zone/container/comp objects to make debugging much easier
* some minor related updates to go along with this
