[GEM-dev] more textCoord fun

Hey all,

I realized some weirdness with textcoords in my patch the spreads one
texture over many geos.

My chain looks something like this:

[gemhead]
[pix_image]   [loadbang]
[pix_texture]-[mode 0, repeat 1 <
[s group]

Then there are 40x30 geos each with:

[r group]
[pix_coordinate]
[separator]
[square]

I've moved separator AFTER pix_coordinate as per cgc's instructions. As
far as I know this is odd in Gem, since the pix_coordinate for each
square is before the seperator they may interfere?

Anyhow When I just this patch the text-cords are all screwed up,
(shifted slightly, actually looks like they are doing square texturing
when they should be doing rectangular). Even once I send the proper
coordinates using my python script.

In order to get everything to display right what I need to do is load
the patch and then manually reinstanciate the pix_texture (clearing the
texture) and then reloading it with pix_image.

Actually now that I think of it that is effectively removing the "mode
0, repeat 1" thing. Hmmm, actually I don't need to set "mode 0, repeat
1" now that I put separator after pix_coordinate...

Anyhow I answered by own question, maybe someone can enlighten me as to
why this is happening.

Thanks all.
