android_vendor_qcom_opensou…/libhwcomposer/hwc_mdpcomp.cpp
Saurabh Shah acf102021a hwc/overlay: Video on 4k2k external, 4k2k rotation. 
-Add support for Video via overlay on 4k2k external panel.
-Add support for rotating videos on 4k2k panels. We use
pre-rotation in hwc to rotate a video into a single buffer,
irrespective of panel size. Then this buffer is fed to MDP.
Rotator objects are managed by the new RotMgr.
-Cleaup mdpcomp and overlay.
