RGBA_8888 rather than BGRA_8888

Hi,

I posted this over at the lineage-rpi forum initially as I wasn't sure what affected the issue:

lineage-rpi/android_frameworks_native#1

I have a series of 3rd party applications that depend on ImageReader being set to RBGA_8888 (0x1) rather than BGRA_8888 (0x5). TeamViewer Host is the main problem:

10-01 13:08:48.644 1986 2960 E AndroidRuntime: java.lang.UnsupportedOperationException: The producer output buffer format 0x5 doesn't match the ImageReader's configured buffer format 0x1.

I have never compiled Android drivers before and don't know enough about low level graphics :(. I can sort of see what may need to change in https://github.com/lineage-rpi/android_frameworks_native/blob/21f013910fd6b7cde6b78fb6d4ac619880ef0e1a/opengl/libs/EGL/eglApi.cpp.

But basically my question is, what is the easiest way to change the system to run in RGBA_8888 and not BGRA. Is this even possible or does it require changing the hardware (Raspberry Pi 3).
