The mirrored first-person model leaves its geometry mirrored; a numeric
display drawn mirrored (rasterizer_set_model_skinning's winding flag) now
shows each digit's bitmap turned over in u (1-u on the first map's texture
transform) and swaps the digits' order across the display (the quad of the
n-th digit from the right shows the n-th from the left; digit count from
the counter limit, the compass's single digit unchanged). Only for 2d,
non-screen-space first maps of numeric chicago/generic shaders, only when
mirrored: right-handed and flat output unchanged.
debug.mirror_first_person (Android, default false): off the headset the
first-person weapon is mirrored across the camera's forward/up plane as
the left hand's is in VR, for checking such things in the emulator.
