* 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().
This change finally introduces gray image rendering with bopti. This
is the final iteration of bopti v2 and certainly the fastest so far.
All four profiles are supported, without change to the format.
