Bug 935: NEWT PointerIcon: Add Toolkit Agnostic PixelFormat and Conversion Utilities (Allowing 'arbitrary' PointerIcon data input)
To allowing 'arbitrary' PointerIcon data input, i.e. via raw pixels
we need to define an agnostic PixelFormat and required conversion utilities.
The latter is not hw accelereated (toolkit agnostic), but this shall be expected
and satisfying for small amount of 'pixels'.
