Hi Bram,

I just had a quick look at the source, and it seems that Performer
should support 1D textures without particular efforts on your part.

Simply set image size accordingly (through pfTexture::setImage),
and it should all work. Note however that you will still have to
provide an array of pfVec2s for your texture coordinates.. the
second float in each vec2 should have no effect (but try setting it
to 0.0 to avoid surprises).

If things don't work as I described, please let me know and I will
take a closer look at it.

Hope this helps,
Regards,
Paolo
