2206097: Broken suggestions while composing message 2166583: Color artifacts with MDP dithering 2261119: Passion transition animations are rough 2216759: Screen flicker when dropdown list in background window shows or hides This is part of enabling GPU composition instead of using the MDP. This change is dependent on another change in the vendor project. Specifically this change disables the use of EGLImageKHR for s/w buffers for cache coherency reasons. memcpy is used instead.
