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.

33680a3800 glcolorbalance: Copy caps in transform_internal_caps()
We don't get ownership of the caps that are passed in, and doing so
causes crashes at a later time.

Fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/546

567bbe3c07 glcolorbalance: Support OES textures for input/passthrough
glcolorbalance is in the default GL path inside glimagesink,
so has been causing an possibly-unnecessary extra texture copy
on Android for a while now. If we're just doing passthrough,
we can support OES directly. If not, they'll be transformed
to 2D textures and colourbalanced.

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

cb0f02c78a glcolorbalance: reconfigure on passthrough changes
Fixes an assertion when moving from passthrough to non-passthrough

Without an explicit reconfigure, glfiter won't have created the GL
resources such as the FBO, GL bufferpool, etc and basetransform will
allocate sysmem buffers instead.

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
and modifying textures.

e3f53deb32 glcolorbalance: create the shader if it doesn't exist in the render callback
Changing the properties may result in glcolorbalance moving from passthrough to
non-passthrough and we weren't creating the shader in that case.

731f9928dd gl: implement a colorbalance element
It performs the exact same operation as videobalance but with opengl shaders and
was tested with glvideomixer by comparing frames from videobalance and
glcolorbalance.
