Fix Bug #480 (attempt) - ATI + WinXP: make context current for ARB PFD queries/selection

TODO: Validate if bug is actually relates to the 'old' ATI Windows driver for old GPU's like X300 etc
and unrelated to the actual Windows version !

Also ensure that the no pixelformat is being set on external context/HDC.
