Only works when switching to fbcon for now. We need to stop
page-flipping when the DRM FD is paused to support switching to another
compositor.

win objects are allocated with `new`, so they need to be de-allocated
with `delete` instead of `free`.

Activate libliftoff's internal log when layers are enabled and the parameter
'd' is provided.
Note: this needs some patches to libliftoff to make the debug readable that I
have proposed upstream.
Trying to layer onto planes should be continued when fb ids are set and
not the other way around. Here the assert also failed when only having
one layer.
It is enough to get the global cursor location when repainting it. So we do not
need to query the relative position. If later on we find this is not right we
should be still able to get the relative position from the surface position
instead of calling into XWayland.
Also it is not expected and apparently unnecessary to move the cursor in the
paint function. Therefore remove this call too.
With cursor position going through global variables we do not need to query the
global position anymore. Remove the MouseCursor function for that.
Furtheron the relative position getter is also not necessary, but let's remove
this one in a separate commit.
This commit also adds a debug line for debugging flaky focus changing.
Many code editiors remove trailing whitespace automatically making patches
difficult since often unrelated lines get changed with the same commit.
So remove the whitespace in the steamcompmgr file all at once in this separate
commit.
For now just mark one repaint per refresh interval without any particular
alignment, as that can be hard to get in nested. We'll use the display
timing extensions for that later.
We'll have it align properly in embedded mode soon.
