675415bf2e gl: try to use highp precision where supported
The use of mediump as a specifier in GLSL shaders will have limited
resolution and when used as texture coordinates may become inaccurate
over texture sizes of 1024.

4952fdd956 gl: do not include GL headers in public gstgl headers
Except for gst/gl/gstglfuncs.h

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

76bf415a96 glfilter: Remove hard-coded pad templates
Add a function to install the default RGBA pad templates,
but don't make them required so that there can be
GstGLFilter sub-classes with different input/output
caps if they want. Remove the hard-coded RGBA restriction in
the set_caps_features call, as it will be taken care
of by intersecting with the pad templates.

Update all the sub-classes to match

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.

7f10822de4 gl: use GLMemory for accessing textures everywhere
This simplifies and consolidates a lot of duplicated code creating

0d1a65e86b gl: enable gldeinterlace on OpenGL ES
1.Porting the exist deinterlace shader and OpenGL callback
  to be compatible with OpenGL ES.
2.Add a our blur vertical shader to gldeinterlace.
3.Add a property named “method” to let user choose which
  deinterlace function to use. Default to choose blur vertical
  method for better performance.

[Matthew Waters]: fix name of greedyh in method property (was greedhy) and port
to git master.

3613ecfd0a 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.
