Hi,

everyone with a CLE266 can play with TextureTriangles() now.

Would be cool to have some nice demo apps ;)

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...
