--- Comment #2 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming.

It seems the game requests a stupid pixel format which causes failure to set up
GL context later.

At one point it calls 'glGetString(GL_EXTENSIONS)' on that GL context which
returns NULL by design since the context doesn't exist due to earlier failure.

Dumping the descriptor:

--- snip ---

The descriptor iPixelType value 0x18  is _hard_ coded from PE '.data' section,
there is no mistake here.

Maybe Windows has a different heuristics here, still finding/providing a match
given that stupid 'iPixelType' value.
