The check wheter a pixelformat is actually supported will happen in 
IWineD3DImpl_CheckDeviceFormatand createsurface should call this function to 
verify wether a format is supported. Checking if a format is supported before 
returning the gl config doesn't really make sense. If the format isn't 
supported and we ask gl for a compressed texture we will get an error 
returned and broken graphics(because we ignore gl errors generally). If we 
pass 0 instead for the gl format and internal format we will have broken 
graphics too but I don't think gl returns an error then(although I'd have to 
check the man page for that)

IWineD3DImpl_CheckDeviceFormat needs a fixup too, like whitelisting formats 
instead of blacklisting them.
