Since commit 6a615d2621 [1], the opaque
region would be set only when running fullscreen. Having it set
properly for the windowed case is helpful to test the overlay path in
compositor-drm.
What this patch does is:
- reverts the above commit;
- remove the "if fullscreen make the window opaque" conditional, that
should have been removed when -o was introduced and was actually the
cause for the bug solved in [1];
- sets the opaque region when running fullscreen, regardless of the -o
switch.
[1] commit 6a615d2621
Author: Scott Moreau <oreaus@gmail.com>
Date: Thu Aug 30 14:44:16 2012 -0600
simple-egl: Only set alpha_size=0 when -o is passed.
v2: - Clarify in the commit message that this does not regress the bug
solved in [1].
- Use the correct sha1 for the reverted commit.
Also make all the callers of weston_surface_assign_output() update the
transform instead. This makes sure that when the surface is assigned an
output its bouding box is valid.
This fixes a bug where a newly created surface would have a NULL output
assigned. This would cause weston_surface_schedule_repaint() to not
schedule a repaint, preventing the surface to be shown until something
else caused a repaint.
This is a more generic fix for the issue solved in 4f521731 where
damage obscured by overlays could be lost in one of the output buffers
due to rapid move of a surface in an overlay plane.
This changes the renderer so it keeps track of the damage in each
buffer. Every time a new frame is drawn, the damage of the frame is
added to all the buffers and the rendered regions are cleared from
the current buffer's damage.
The generic module loading must be used now to load xserver.so.
Option --xserver was removed by
a6813d2887.

Add cursor and anchor positions as arguments to the set_surrounding_text
request. The cursor and anchor positions are relative to the surrounded
text, so it does not make sense to have that separate. Remove the

the corresponding event in input-method-context and add support for it

When accumulating damage in the surfaces into the primary plane damage,
regions obscured by the opaque region would be excluded. This causes a
bug when a redraw of a surface is obscured by an opaque surface on
another plane. The drawing to the former surface is clipped but
its damage is never added to the primary plane and is just lost. Moving
the opaque window later reveals the not-up-to-date content below it.
The existing algorithm had some corner cases (pun!), where it failed to
produce correct vertices in the right order. This appeared only when the
surface was transformed (rotated). It also produced degenerate polygons
(3 or more vertices with zero polygon area) for non-transformed cases
where the clipping and surface rectangles were adjacent but not
overlapping.
Introduce a new algorithm for finding the boundary vertices of the
intersection of a coordinate axis aligned rectangle and an arbitrary
polygon (here a quadrilateral). The code is based on the
Sutherland-Hodgman algorithm, where a polygon is clipped by infinite
lines one at a time.
This new algorithm should always produce the correct vertices in the
clockwise winding order, and discard duplicate vertices and degenerate
polygons. It retains the fast paths of the existing algorithm for the
no-hit and non-transformed cases.
Benchmarking with earlier versions showed that the new algorithm is
a little slower (56 vs. 68 us/call) than the existing algorithm, for
the transformed case. The 'cliptest f' command before and after this
commit can be used to compare the speed of the transformed case only.

We can now load any number of general modules, and the shell and xwayland
are just two of them. We continue to use the mechanism for testing but
custom input drivers or logging mechanisms, for example are other use cases.
We rename it flush_damage() as it's the point where we update our rendering
API source (eg, the gles2 texture) according to the accumulated damage,
if necessary.
We move the EGL and GLES2 output repaint code into a new gles2-render.c
file. The eglMakeCurrent, glViewPort, surface loop etc was duplicated
across all backends, but this patch moves it to a new file.
surface_accumulate_damage() will call surface_compute_bbox() with the
extents of the surface damage region, for transformed surfaces only. If
there is no damage, surface_compute_bbox() will round up the empty
rectangle to a 1x1 rectangle. Triangles are produced for this 1x1
rectangle intersected with the surface.
The problem showed up with the triangle fan debug, where some seemingly
garbage pixels showed up relative to rotated surfaces.
Fix this by explicitly checking, that the area, for which a bounding box
is being computed for, is not zero.
Note, that the bbox will also be empty if only one of width and height
is zero. We do not paint things with zero thickness.
