Add support for RGBA128F and RGB96F formats.
IGT wants to add support for planes with a bit depth >10, which
requires a higher precision format than we have currently.
I'm using RGBA as format, because of its existence in OpenGL.
With the new formats we can directly convert our bytes to half float,
or multiply a colro vector with a matrix to go to the Y'CbCr colorspace.
This requires pixman 0.36.0, so bump the version requirement.
