956c4d0bde gl/format: use our own GL format enum's instead of gstvideo's 
They can describe in more detail (such as component sizes) the requested format.

b1fd1d34bd gl/effects: use non-PBO GLMemory for internal textures 
middle textures in gleffects do not need to use GstGLMemoryPBO as they
aren't transfering data to/from the GPU. This will cost too much DMA
memory and cause performance issue. Change the allocator to use non-PBO
GstGLMemory.

3f7b549881 gl/utils: move gen_shader() to the plugin and remove del_shader() 
gst_gl_context_del_shader() can be replaced by a g_object_unref().
gst_gl_context_gen_shader() should be replaced by using GstGLSLStage.

cafcde5586 glfilter: remove display_init/reset 
They are mirrors of GstGLBaseFilter's gl_start() and gl_stop() virtual methods
so use them instead.

aa109016a3 gl: use GLMemory for accessing textures everywhere 
This simplifies and consolidates a lot of duplicated code creating
and modifying textures.

4e7797546a gleffects; give each effect a unique long name and description 
Gives applications that scrape the factory details more detailed and unique
details on the exact element.

8c02a47741 gleffects: fix shader compilation with legacy opengl 
All the gleffects shaders can be run against a gles2 or a legacy opengl glsl
compiler but weren't being advertised as such.

Fixes gleffects under desktop opengl < 3.2.

b25807c382 glshader: port to using GstGLSLStage objects for string management 
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program.  The uniform/attribute
interface has remained the same.

b7777b9181 gl: use gles2 shaders everywhere

ba5bf50d5f 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.

c638477c48 glfilter: Remove onStart/onStop vfuncs, and unused onReset() 
onStart/onStop are just duplicates of the basetransform ones, onReset
was never called but was used everywhere when stop should've been used.
