By convention, the channel order of __DRI_IMAGE_FORMAT_ is the
opposite of that of PIPE_FORMAT_. For example,
__DRI_IMAGE_FORMAT_RGB565 maps to PIPE_FORMAT_B5G6R5_UNORM.
As for HAL_PIXEL_FORMAT_, there is no rule... The switch-statement in
st/egl defines what a HAL_PIXEL_FORMAT really means. As for egl_dri2
here, I will add this comment
/* see the table in droid_add_configs_for_visuals */

Yeah, I forgot EGL_WAYLAND_BUFFER_WL is cross-platform. Will move
this to platform_android.c.
