[GEM-dev] mipmapping and pix_snap2tex and GEMgl*

[cyrille henry]

hello,

i'm not familiar with mipmaps, but i've got the impression that you have the solution :
a new object GEMglGenerateMipmap, with a 2nd inlet for the texture look a good solution for me.

cheers

This would defer the problem to the patch level, an automagic system to track when mipmaps need to be regenerated would be a lot more work and probably break some bizarro use cases where mipmaps shouldn't be regenerated.
