Hi,
this patch makes it possible to have high quality texture filtering
with the pure software renderer. The main purpose is to use it with
osmesa. The anisotropic filtering is based on Elliptical Weighted Avarage (EWA).
The patch was designed to make as little changes to the existing codebase as
possible. Therefore, the existing texture_sample_func
signature has not been adjusted although this was required; a "hack"
was used instead to pass the required arguments.
I provide this patch as other people might be interessted in
using anisotropic filtering for osmesa, especially when rendering
images in a headless environment.
Thanks. I'm about to commit your patch (with some formatting fixes).
Would you be interested in implementing this feature in the Gallium
softpipe driver too?
