86Box with PowerVR PCX2 emulation 0.1

First test release of 86Box with an emulated PowerVR PCX2 (Matrox m3D) card.

It runs the real Matrox m3D drivers (tested with the retail 4.1.1 driver) as a second
graphics card beside the emulated 2D card. Frames from Moto Racer, Shadows of the Empire,
Ultim@te Race, Quake, Unreal and MDK were drawn on a real m3D and compared pixel by pixel;
every one matches to within 13 of 307,200 pixels, and most exactly.

Known limits: render time is fixed at 7.6 ms per frame, PCX1 boards (Apocalypse 3D) are not
emulated, and MechWarrior 2 is untested.

Hardware, testing and direction by Z2k Retro. The emulation, tools and documentation were
written with substantial help from Claude, Anthropic's AI model; every result listed above
was checked on the real card.
