[vbox-dev] bug in H3DOR_FMT_RGBA support for offscreen framebuffer redirection

While implementing 3D redirection in my framebuffer I think I've discovered
a bug - the H3DOR_FMT_RGBA format is not handled properly. If you look at
display_vrdp.cpp:345 then if the returned strings do not match
H3DOR_FMT_RGBA_TOPDOWN then successful return code is returned but the
initialization functions are called which results in my framebuffer getting
a null pointer in all the instance parameters passed to the calls. I guess
since the vrdp server sets both everything goes fine and only issues can be
experienced with external framebuffers.

What is more interesting to me - is H3DOR_FMT_RGBA going to be supported? I
am mixing the contents of the GPU framebuffer and the offscreen OpenGl
surface and having to rotate the latter makes a bit of an inconvenience
