When using the fb backend at 24bpp it allows a visual with 32 bit depth.
When using CopyArea from a 32bpp pixmap to a window with a 32 bit depth it would
read the ARGB as RGB.
Fix is to correctly ignore the alpha channel in the pixmap when copying.

When using the fb backend at 24bpp it allows a visual with 32 bit depth.
This would cause RENDER to try and create an invalid pixman buffer and hit the
following assertion when trying to render to it:
