ccc410e73c glimagesink: Don't do pool caching 
We now know that pool caching can cause renegotiation issues
when an element in the pipeline change from passthrough to not
passthrough. As it's not needed, don't cache existing pools.

2210ba5d46 glmemory: separate pbo transfer from texture transfers 
When supported, the potentially longer pbo upload/download can be
initiated before the texture upload/download, potentially increasing
throughput.

9900928403 gl/window/x11: only listen on the X Display when needed 
5697b6b89b causes us to possibly listen
on a toolkit provided Display connection.  We thus could eat their
precious winsys events.  Only listen if we need to
(!foreign_display or videooverlay).

5007311198 glfilter: Add transform_internal_caps() vfunc 
Add a vfunc that is called by glfilter before it sets
caps features and intersects with the peer caps, and
move removing the size from caps into its default
implementation. Allows sub-classes to do more
sophisticated management of the size fields in case they
don't support arbitrary resizing or have distinct
preferences.

697107fe7d glfilter: Don't remove size fields from caps

like videoscale does, so the caps are clearly unfixed in
all cases.

fce0e0ba3c gl: add and use gst_gl_internal_format_rgba 
Previously when compiling GstGL with both GL and GLES2,
GL_RGBA8 was picked from GL/gl.h. But a clash may happen at
runtime when one is selecting GLES2.

gst_gl_internal_format_rgba allows to check at runtime
if it should use GL_RGBA or GL_RGBA8.
