* Add WIP support for Vertex Program A, add the FADD_I32 shader instruction, small fix on FFMA_I encoding, nits * Add separate subroutines for program A/B, and copy attributes to a temp * Move finalization code to main * Add new line after flip uniform on the shader * Handle possible case where VPB uses an output attribute written by VPA but not available on the vbo * Address PR feedback
