That's usually the idea. However, not set_gfx_mode since there are some
drivers that specificly ignore values, or that don't need proper arguments.
GFX_TEXT, for example, is typically passed four 0's. GFX_SAFE will ignore the
width/height if it couldn't first set them, and fall back on default values.
Most non-speed critical functions already ASSERT on explicitly invalid values.
(you generally don't want to ASSERT on undefined values, since they could be
used later; only ones that are explicitly stated as invalid).
