Thanks!

I'm hoping to get a beta version out by the end of next weekend, and to
make an official release a couple of weeks after that. But that is
strictly an estimate: please don't hold me to it should things take
longer!

The only major task remaining is for me to rewrite the perspective
correct texture mapper in asm (I did the gouraud and affine mapped
routines last weekend), and try to get it going at a decent speed. Since
it uses floating point math, and I've never written any FPU asm before,
it may take a while, but I should be able to get a big speed increase
over the current C version. The code gcc produces for this routine is
really bad: it issues a floating point div instruction, and then
immediately refers to the result of the division. In asm it will be
possible to overlap the divide with other integer operations, so it will
happen essentially for free...
