Set MOBILEGL_USE_ANGLE=1 to run DirectGLES replay with packaged ANGLE
instead of the device system GLES driver.
Set MOBILEGL_TRACE_ANGLE_VARIANT to the packaged ANGLE short hash used by
DirectGLES replay.
Set MOBILEGL_RETRACE_USE_PBUFFER=1 or pass --use-pbuffer to run DirectGLES
against an offscreen EGL pbuffer instead of the Activity surface.
Pass --avoid-angle-llvmpipe-sampler-mipmap-min-filter for DirectGLES traces that
need ANGLE llvmpipe sampler mipmap filters downgraded to avoid driver stalls.
Pass --coherent-as-flush for traces whose engine writes persistent
GL_MAP_FLUSH_EXPLICIT_BIT maps it never flushes (MOBILEGL_COHERENT_AS_FLUSH=1).
