Make sure we reformat HDR content with a gamma of 2.2 when rendering
to a SDR surface and linearize SDR video content when rendering to
HDR surfaces
This look very good for SDR content, but the tone mapping for
HDR->SDR could still be improved.

Get rid of some code duplication and share the uniform buffer that we
use across our shaders, so that we will only need to modify it in one
place in the future.

Somehow we ended up having the wrong bit swizzling in the shader for
the GL_TEXTURE_RECTANGLE shader.
Also add some explanation about the SamplerRect pixel format to the
documentation.
Pick-to: 6.2 6.3

Needs its own dedicated shaders and logic because we have to deal with
OpenGL textures for the GL_TEXTURE_RECTANGLE.
This will currently be functional only if the core video buffer is of
the type kCVPixelFormatType_32BGRA.
Pick-to: 6.2
