Re: BUG in function "ir_texture_convert_rave_filter" ?

[Daniele C. <dca...@in...>]

If I use "TQ3PixmapDrawContextData" instead "TQ3DrawContextData" and I set 
"Q3InteractiveRenderer_SetRAVETextureFilter" with "kQATextureFilter_Fast" 
the render of texture is not correct.  If I use "kQATextureFilter_Mid" or 
"kQATextureFilter_Best "  render is ok.
I thought the problem was "oglFilter.magFilter = GL_NEAREST" in 
"ir_texture_convert_rave_filter" function . You can see an examples with 
"oglFilter.magFilter = GL_NEAREST" at link 
http://www.interstudio.net/quesa/nearest.JPG
and an examples with "oglFilter.magFilter = GL_LINEAR" at link 
http://www.interstudio.net/quesa/Linear.JPG
I used  windows  I don't know if with mac os there is the same problem.May 
be the problem in other part of code?
