6083ad6287 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

78e91a731f 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.

5da138d1ae 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.

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

5c4e724f70 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.

1bb2985777 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.
