This is skanky Quartz Composer plugin, environment macro, that transforms the GL Texture matrix.

GTTextureTransform from George Toledo on Vimeo.

...so, this means that in this environment you can do things like zoom, offset, or rotate texture through OpenGL function.

For example, one can rotate the texture on a sphere while keeping vertex positions the same, or one can zoom image on a sprite without using core image, etc.
