This parameter controls the maximum number of glyphs to print.
For backwards compatibility, it is automatically inserted by a macro in
older calls with only 7 parameters.
* Turn on GCC's -O3 for bopti files
* Remove the bopti_render_noclip() step
* Use rbox as early as possible to avoid moving memory around
* A lot of local grinding
* Defined the single-column single-position (SCSP) situation where a
single column of the input is blit on a single position of the VRAM.
Provided optimized assembly and a specialized bopti_render_scsp()
function.
* Improved the rendered by reducing the amount of computation and
clarifying the semantics of the rbox.
* Separated rbox setup from clipping by making bopti_render_clip() a
purely abstract superset of bopti_render_noclip().
