scene/item: restrict frame callbacks based on the output rather than geometry
Sending frame callbacks based on whether or not the bounding rect intersects
with the
rendered output has two big problems:
- when a window is entirely off-screen, it never gets frame callbacks. This is
particularly
problematic when the application waits for frame callbacks to render the next
frame, but
KWin waits with moving them to an output until the application commits the
surface
- when a window is on two outputs at once (like with cloning), then it gets
twice the
amount of frame callbacks - which means the application ends up rendering
twice as
fast, which doesn't make any sense
This commit replaces that approach with just checking if the output is the same
as the one
Workspace picks for the center of the window. If the window is entirely
off-screen, that
will still result in an output getting chosen, and it also can't be on two
outputs at once.
