this came in a patch that I take full responsibility for not adequately reviewing at the time.
the names are confusing and counterintuitive, and it does not properly include the client namespace.
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
this fixes some issues in the new randr2 code that made it not work
right with plug/unplug and lid close/open. now it does work right and
plugging/unplugging displays is seamless (if your driver does not give
plug/unplug events bind a key to update screen config acvtion and e
will figure it out when you hit the key).
the problem is something changes window gravity... what i don't know,
but hey - just forcibly move window to 0,0 which is where we expect it
anyway when resizing.
@fix
the dialog for now is simple and lets you just raw edit the properties
per screen in a dialog. nothing fancy. not user firendly. but it works.
the randr core has been totally rewritten and tested against a range
of drivers and setups before even getting a commit. it works solidly
and configures screens reliably now. drivers tested:
nvidia
intel
radeon
some drivers still are unreliable in terms of delivering plug/unplug
events for outputs (both intel and radeon are flakey - nvidia is solid
and reliable). so to fix this there is now a screen redo action you
can bind to a hotkey or something and have e re-evaluate current
screen setup and apply ny pending config if needed.
also to make reconfiguring prettier the screen is faded to black
first, then configured, then faded back in. some drivers work
flawlessly with this, others still flicker some garbage.
i admit - i haven't tested nouveau, but my general take on this is the
randr code is now in far better shape than where it was (minus pretty
and easy dialog). the dialog can be done next, but i'd like to get the
core in now for more testing.
@fix
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
according to the shape extension protocol, the number of rectangles returned should be checked to determine a client's shape. if 0 is returned, the client has no shape, meaning that it either should not be drawn or should have no input region. this improves behavior with various client window types such as tooltips
ref T1820
this addresses a vbox gl asccel issue where gl client apps can cause
al of vbox to crash and users find it unexpected that e is set to
software compositing but apps go and use opengl, so it's more
consistent for users
