3bff135503
Previously we hardcode wide color gamut in HWUI as scRGB color space with FP16 pixel format. However, the hardware composer doesn't support this combination. This patch plumbs wide color gamut composition preference from composer API to HWUI such that HWUI can now pick the combination of color space and pixel format for the surface. BUG: 111436479 Test: Build, flash and boot, verify with a demo app. Change-Id: I7a8b4d8deca72ef40069dba9d23a3f5e90dbfe5a
