Better Texture coordinate management

I'd like to be able to use sub-textures from a single page. Be able to control the start and UV as well as the tiling parameters. However, I understand that that may decrease Linden revenue for texture uploads but it would increae performance by decreasing state changes due to textures.

Technically, the Lindens don't make money from texture uploads. The L$10 upload fee is just a money sink, to draw money out of the economy. It doesn't go anywhere, it just disappears.

It's a good idea, though. You should talk to Neil Protagonist -- he has some mockups of something similar.

I know this is probably going to be controversial but I would like to add multipass texturing. Or at least a second alpha pass - you can do a lot with a base tiled textured and then alpha a noise texture over it that repeats at a slightly different rate.

Obviously, I'd like a complete shader system but I'd settled for sub-texture pages and a dual pass system. That would probably satisfy 90% of the requirments.

Programmable shaders using LSL sounds about right to me. I'm suprized this wasn't a feature to start with.
