Fixed FreeType module to build with FreeType versions older than 2.1.7. Fixed typo. Added vtSema to protect call of driver DPMS function. removed unneeded variable Modified RandR driver hook to reduce the number of function calls to one. Function is sufficiently generic to be extended in the future.
