Support forcing all screenshots into a CPU consumer

Looks like a full GPU path is less efficient on some GPU
drivers that we're still using, and CPU is reliably faster...
(there's probably a locking condition going on somewhere, this
needs to be looked into)

    surfaceflinger: odd hw rotation (90/270) patch for swapping width/height

    This patch works in addition to the following commit
    re-implementing ro.sf.hwrotation:
    https://github.com/CyanogenMod/android_frameworks_native/commit/7d283431efffc4402cb1a6cacf5da64729c883bb

    When using values of 90 and 270 for ro.sf.hwrotation the
    LCD width and height also need to be swapped to display properly.

    NOTE: This patch does not fix the initial startup of bootanimation
