#29 allegro 0.2.2 mipmaps don't work

[Mike Farrell]

I use allegroGL 0.1.0 on linux and I haven't been able to upgrade
to the new allegroGL because as soon as I recompile all of my
programs, the mipmapping is screwed up.

No matter what I try to do to fix it, the mipmapped (distant)
textures are blocky. It's as if I passed
GL_NEAREST_MIPMAP_NEAREST to the mag filter parameter
though I haven't.

I never had this problem with 0.1.0

Have you tried using allegro_gl_use_mipmapping() or
allegro_gl_make_texture_ex()?

Yes, tried both

Does it affect the examples too?

None of the examples use mipmappin in a way that I can test.
I have to be wandering in a 3D scene and watch the
transition of the mipmaps in the distance to tell if they
are being filtered wrong.

I would imagine though that the examples would have the same
problem because I have produced very basic mipmapping
example programs of my own that have the problem. I also
believe I tried nehe tutorials on the new library that
produced the problem as well.

I have the same problem with version 0.2.4. Old version 0.1.4
worked ok. Here are the links to two screenshot:
http://bwpow.ideaz.sk/supreval/good.jpg (ver 0.1.4)
http://bwpow.ideaz.sk/supreval/bad.jpg (ver 0.2.4)

Source code for both versions is exactly the same. In 0.2.4
version are small textures very blocky (light on the ground)
and textures seems to ignore GL_CLAMP_TO_EDGE flag. Same
for distant textures.

I use allegro_gl_use_mipmapping() and
allegro_gl_make_texture().
