clutter/x11: Fix build without libwacom
When libwacom is configured disabled, this error appears:
../clutter/clutter/x11/clutter-input-device-xi2.c: In function ‘clutter_input_device_xi2_finalize’:
../clutter/clutter/x11/clutter-input-device-xi2.c:122:7: error: ‘device_xi2’ undeclared (first use in this function)
if (device_xi2->inhibit_pointer_query_timer)
Fix it with the "obvious" solution.
This code was added in c1303bd642e57d53ccbc8f6eb450c2a45bf4d3ef.
When a user moves their cursor the perceived behaviour is that it will
pick what is under the cursor. However this isn't how picking works.
Picking does a virtual redraw of the screen, so in some cases what gets
picked isn't the same as what the user could see on the previous frame.
It more represents what will be drawn on the next frame than what is on
screen at present.
It may be unsafe to change these semantics, and they are useful anyway.
Just document it better.
cursor-renderer: Align OpenGL cursor rect to physical pixel grid
When stage views are scaled with fractional scales, the cursor rectangle
won't be aligned with the physical pixel grid, making it potentially
blurry when positioned in between physical pixels. This can be avoided
by aligning the drawn rectangle to the physical pixel grid of the stage
view the cursor is located on.
wayland/cursor-surface: Update sprite when attaching NULL
Attaching a NULL buffer should hide the cursor sprite. In these cases,
we we'll have neither surface nor buffer damage, so also update when we
just attached a NULL buffer.
wayland/surface: Clear texture when attaching NULL
When 252e64a0eae61735a912d41817c6e6f24824146b moved the texture
ownership to MetaWaylandSurface, it failed to handle the case when a
NULL-buffer is attached, leaving the texture reference in place. This
caused issues when the surface should have been hidden (e.g. attaching a
NULL buffer to a cursor surface for hiding the cursor sprite).
