[Fluxus] texture not rendering

[gabor papp]

hi Paraita,

thanks for reporting the bug. it is fixed in git now.

the new multitexture detection code caused this on machines where
multitexturing was disabled. MAX_TEXTURES is set to 8, and when the
textures are actived the first one was actived, but the rest was
disabled. this disabled texturing when there is no multitexturing.

since it's a serious bug, i think it calls for a new 0.16 release.

best,
gabor
