Hi,
everyone with a CLE266 can play with TextureTriangles() now.
Would be cool to have some nice demo apps ;)

include : directfb.h
src/core : gfxcard.c gfxcard.h
src/display : idirectfbsurface.c
Log message:
Added IDirectFBSurface::TextureTriangles() which takes a source surface
as the texture, a pointer to a DFBVertex array, the array size and the
DFBTriangleFormation which can be DTTF_LIST, DTTF_STRIP or DTTF_FAN.
Each DFBVertex contains transformed x, y, z, w, s and t coordinates
using some fixed point integers.
The set blitting flags are used.
Implemented textured triangles for CLE266 (only DTTF_FAN yet).
Started a Matrox implementation, but don't know how to calculate
perspective coordinates for the trapezoids (s, t and q).
The added code is very small, but applications can now render full
3D scenes with alpha blending, color modulation (for lighting) etc. ;)
But be aware of the missing Z buffer...
