Fix colorspace transform with multitexture color text.

Color text glyphs can be stored across multiple atlas textures, which
requires sampling from one or another texture. However, if we use
multiple appendTextureLookup calls with the same colorspace transform
helper, it ends up generating multiple copies of its helper functions.

Instead, we will pick our texture, sample its value, and apply the
colorspace transform to the result outside the if-then-else block.
