ProgramState::setTexture()on each call creates newTextureInfo, which allocates new vectors, and then assigns it to anotherTextureInfofreeing old vectors and moving the new ones. This optimization removes these redundant (de)allocations by setting the values directly and reusing the old vectors if possible.
