8a1d31f6ab 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.

b3d8e09839 glfilter: rewrite subclasses for filter_texture() occuring on GL thread
There's no need for the jump to an extra thread in most cases, especially
when relying solely on a shader to render.  We can use the provided
render_to_target() functions to simplify filter writing.

4bbda2b626 glframebuffer: rewrite for a more consistent API
Facilities are given to create fbo's and attach GL memory (renderbuffers
or textures).  It also keeps track of the renderable size for use with
effective use with glViewport().

2d62b2910c gl: take the affine transformation in NDC
Provide a function to get the affine matrix in the meta in terms of NDC
coordinates and use as a standard opengl matrix.

Also advertise support for the affine transformation meta in the allocation
query.

86110c4765 glupload: always add texture-target field to GL caps
1. Various elements/base classes only perform a subset check on accept-caps
2. Some GL elements have texture-target in their pad template
3. When checking subsets, only the caps to check are allowed to contain extra
   fields.  If the 'template' caps have extra fields, the subset fails.
Thus without texture-target on the caps, various accept-caps implementations
were failing.

Also, add some convenience functions for setting and retrieving
texture targets to/from GValue.

c486b1b3b0 gl/utils: add a function to insert a debug marker
These markers are visible in tools that record the GL function calls
such as apitrace, et al.

Makes it easier to match up GL draw commands with specific elements.

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.

c2471aec81 gl: add EGLImage support
* picked from old libgstegl:
  - GstEGLImageMemory
  - GstEGLImageAllocator
  - last_buffer management from removed GstEGLImageBufferPool

* add-ons:
  - GstEGLImageMemory now old a reference on GstGLContext
    so that it can delete the EGLImage and its gltexture source
    while having the associated gl context being current.
  - add EGLImage support for GstVideoGLTextureUploadMeta which
    mainly call EGLImageTargetTexture2D
  - GstGLBufferPool now supports GstEGLImageAllocator
  - glimagesink / glfilters / etc.. now propose GstEGLImageAllocator
    to upstream
