This is a bit of a hack for now (need to look into maybe using cmem),
but it gets 32-bit windows working for all but the software renderer
(probably just refdef (and maybe viddef) getting out of sync with the
assembly code.
The plan is to have a fully component based entity system. This adds
hierarchical transforms. Not particularly useful for quake itself at
this stage, but it will allow for much more flexibility later on,
especially when QuakeForge becomes more general-purpose.
