Scale surfaces based on output scale and the buffer scale set by them.
We pick the scale factor of the monitor there are mostly on.
We only handle native i.e non xwayland / legacy clients yet.

Advertise the scale factor on the output and transform pointer and damage
events as well as input and opaque regions for clients
that scale up by themselves i.e use set_buffer_scale.
We do not scale any 'legacy' apps yet.

Since commit 6e8d1d79d, move operations are always performed for
the (toplevel) parent of all transient, which is just plain silly
if the dialog is not actually attached to its parent (either because
the dialog is not modal or the setting is disabled).
We need the old rect for two purposes: to find the x/y in a resize-only
action, and to pass into the constraints code for nefarious purposes.
The constraints code takes a frame rectangle, so we convert the original
client rect into a frame rect, but never convert it back since it's
unused for the rest of the function.
Instead of playing games with the variables, just have two,
separately-scoped variables. One is the client rect, the other is the
frame rect.
Ugh. So in the fullscreen case, we need to make sure to specify that
it's a MOVE_ACTION so that we move to the saved position, but we
can't do that in the resizing case since we need to use the resized
rectangle.
The flags are really hurting us here. Perhaps we should make it the
client's responsibility to specify a complete rectangle which we
could resize to; then the weird-o logic would be self-contained in
each front-end.
I'm not convinced this covers all cases, especially when we could have
a dangling weird state pointer, but it fixes our existing two testcases.
For gravity-based resizing, we need to make sure that the requested
rectangle has the proper x/y position given by the gravity resize,
rather than the bogus root_x_nw / root_y_nw parameter.
Make the test for this more explicit.
When an actor carrying canvas content is repainted, it will currently reupload
the data from the buffer to a texture. While this is not a performance problem
on a desktop, some mobile environments take a big performance hit. This
change tracks data changes and only recreates the texture if necessary.

This can happen when we dpms off the output or when login1 takes away
drm master status from our drm fd. In either case, we need to call
the swap notify handler so that the compositor dosn't get stuck waiting
for that notification. The compositor should stop repainting shortly in
both cases, as it's either going into dpms off mode or vt switching away.

This environment variable predates the reliable platform detection in mesa
and typically just causes crashes when the specified platform doesn't
match what's passed in. Aside from being unecessary and problematic
it also leaks into the GNOME session, preventing clients from
automatically detecting the wayland platform.

Restoring the position in our move_resize_internal implementation
is too late. We need to do it at ack-time, before we hand off the
new position to the constraints code.
