-/**
- * \file lower_texture_projection.cpp
- *
- * IR lower pass to perform the division of texture coordinates by the texture
- * projector if present.
- *
- * Many GPUs have a texture sampling opcode that takes the projector
- * and does the divide internally, thus the presence of the projector
- * in the IR.  For GPUs that don't, this saves the driver needing the
- * logic for handling the divide.
