We are in the process of removing all _EXP suffix mangling for
experimental APIs (Ref: c6528c4b6c) and adding missing gtk-doc
comments so that we can instead rely on the "Stability: unstable"
markers in the gtk-doc comments. This patch tackles the cogl-texture-3d
api symbols.
This patch also replaces use of CoglHandle with a CoglTexture3D type
instead.
Finally this patch also ensures the CoglTexture3D constructors take an
explicit CoglContext pointer but not a CoglTextureFlags argument,
consistent with other CoglTexture constructors.
