With commit 62ab6891db, 'clients/simple-egl: Handle buffer
scale and transform' we changed the way we resized the client, by
encapsulating the resize in update_buffer_geometry() function.
we didn't correct that when creating the EGL window, which might be
problematic if you attempt to start the window with different a
different state, like maximized.

If weston-simple-egl is run with the "-b" flag, it will attempt to set
the swap interval to 0 during create_surface. However, at that point, it
will not have made its EGLContext current yet, causing the
eglSwapInterval call to have no effect. To fix this, wait until the
EGLContext has been made current in init_gl before updating the swap
interval.

Commit 62ab6891db intended to change the angle calculation
so that the a time delta since the first frame would be used
instead of the absolute time. That was done in order to ensure
the angle would always start with the same value, allowing users
to differentiate left and right, which again is needed when
testing flipped transforms.
However, the `benchmark_time` variable is unsuitable for that
purpose as it gets reset on each benchmark interval, abruptly
changing the angle.
Thus introduce a dedicated variable.

Buffer scale is common enough in the modern desktop space to
expect average GL clients to handle it. Thus lets include it into
our main example client.
While on it, also handle buffer transforms. It's essentially free
for GL clients in terms of computing power but may increase the
chance that Wayland compositors are able to hit scanout fast paths.
Thus having an example client for it is likely valueabel for client
and compositor developers.

Setting the opaque region correctly is common source of error for
clients that simply want to express that a whole surface is opaque.
This is especially true once buffer_scale and buffer_transform come
into play, as unlike for damage, where buffer_damage is the
encouraged and user friendly way today, opaque regions are always
in logical coordinates.
As faulty opaque regions don't have a visual impact in these cases
but only increase resource consumption, these errors often remain
for long times. See
1e2bc68171
for one of many examples.
Give an easy example how to set the opaque region in a conformant
and reliable way.

Rather than creating the wl_egl_window at the same time as wl_surface,
do it after we get the first configure event.
With it, we also defer eglMakeCurrent() as according to the spec, the
first time a OpenGL or OpenGL ES context is made current, the viewport
and scissor dimensions are set to the size of the draw surface.
This is particulary important when attempting to start simple-egl either
as fullscreen or as maximized, as not doing so will either incorrectly
commit a buffer with the original dimensions, and later on to resize to
the correct dimensions (which is the case for fullscreen), or it will
terminate the wayland connection abruptly due to xdg-shell protocol
violation, with a mismatch for the client's geometry (the case for
maximized).

When setting the window as opaque or fullscreen (which creates an opaque

simple-egl.

Constraining the buffer size of an EGLConfig to 32 means that
the sum of red, green, blue, and alpha channels must equal 32.
This constraint prevented weston-simple-egl from picking an
RGBX pixel format when an opaque surface was asked for, since
the typical RGBX pixel formats have buffer sizes of 30, 24,
and 16.

All these have the printf format string wrong. "%*s" sets the field width but
does not limit the string to len bytes. You need to set precision instead to

In the simple examples in which keymap is not handled, the open
descriptor has to be properly closed.
After each suspend/resume sequence the keymap is send again to
every client. On client weston-simple-egl the leak causes a
segfault when no more file descriptors can be opened.
Close the file descriptor and lazily copy/paste the comment

wl_surface_damage_buffer landed ages ago, but in order for GL to
use it the client must bind a wl_compositor version >= 4 (the
version where damage_buffer was introduced).
This patch updates the bind version and allows
eglSwapBuffersWithDamage to actually use the provided damage
rectangles instead of performing full surface damage.
This log is much longer than the patch.

So that we can test the per-surface ZERO_COPY flag:
- start Weston on DRM backend
- run ./weston-simple-egl -o (need to be opaque to end up on overlay)
- hit debug key 'V' to enable the (broken) hw overlays
The debug key is used by first hitting Mod+Shift+space, then hitting 'v'.
Enabling overlays should change the flags from 0x7 to 0xe. To verify the
window is really on an overlay, use debug key 'S' to tint all
GL-composited things green.
This patch is not intended for upstream.
