57a74c156b [client] egl: set a default scale for textures without filters 2021-08-09 18:24:33 +10:00
Geoffrey McRae
6882e5c59f [client] egl: provide the texture scale to the desktop shader 
If the texture has a post-processing filter that has scaled the texture,
the desktop fragment shader needs to know this if it's doing linear
scaling.

53461d7515 [client] egl: simplify desktop vertex shader 
In GLSL, using the / operator on two vectors of the same size divides the
vector component-wise, i.e. vec2(a, b) / vec2(c, d) == vec2(a / c, b / d).

9b87f4ba5e [client] egl: cycle through multiple textures for dmabuf 
This avoids race conditions in GL drivers when attempting to render and
call glEGLImageTargetTexture2DOES on the same texture.

Also, when using glEGLImageTargetTexture2DOES, we do not need to allocate
storage for textures.

1fd726eed7 [client] x11: be less sensitive to frame skips 
External events like launching other applications can cause latency

b3db1ba10b [client] egl: eliminate GLsync object leaks 
It used to be the case that we overwrite this->sync even if it was non-zero
when updating the texture, without deleting the sync object. If we update
faster than we render, the result would be leaking sync objects.

This commit ensures that sync objects are deleted when they are replaced.

5d5e4ede1a [client] egl: use new EGL damage count semantics 
After the damage queue PR, EGL damage count 0 means no change, and -1 means
invalidate the entire window. However, several other places have different
semantics, and we are not handling them correctly:

1. KVMFR uses 0 to signal invalidating the entire frame, so if we receive 0
   rectangles in egl_on_frame, we should set damage count to -1.
2. The damage overlay treated 0 as full damage, which is now incorrect. This
   is fixed, and now it treats 0 as no update, and -1 as full damage.
