[android] allow to run on Android 6.0

NOTES:
regs.window_origin.flip_y MUST flip the y coordinate of any given FragCoord, we don't emulate this, this is the root cause of the error, but I'll just revert for now since it's easier

DON'T MERGE unless it's near 0.0.4 and I (or someone else) hasn't tackled this yet properly

This reverts commit 17fe74ef11.
