Public bug reported:

[Impact] 
 * The fix for bug #1308515 prevents rotation from being used.
 * Rotation support should be added to the intel driver to maintain feature parity when optimus is used vs when not in use.

[Test Case]
 * Run xrandr --output SOMEOUTPUT --rotation left
    - Expected: Screen should rotate.
    - Bad behavior: Succeeds, but causes a black screen. OR the call fails, and screen is not rotated.

[Regression Potential] 
 * Will probably regress when modesetting is used, a separate patch might be needed to disable transforms on modesetting. Will have to be tested.

[Other Info]
