Hi Roman,

Of course not ... here it is:

Although I don't understand / it does not mention all the details it
seems they let produce those alpha-masks by doctus and indeed upload
those alpha-masks to vram which seems to cause performance-problems
for simple operations covering large areas.
What I still don't know is how these alpha-masks look in detail and
wether the "normal" rendering is done? I guess the mask is used as
mask and then "painted" with color ;)

Btw. I read in your blog that you've done a rasterizer - whats the
state of it, or the renderer implemented by Jim? I am just looking for
a simple one to lern/"reserach" a bit in this topic.

Thanks, lg Clemens
