It's a bit of the long-and-short of graphics and formats is all.

There's raster graphics and there's vector graphics,
there's procedural graphics, it results being to or
from raw or bitmaps, or according to box or drawing fonts,
a drawing context, say, the bpp and the ppi and the
color model, that for rendering fonts is a particular
sort of language itself combining bitmap and procedural
graphics and size hints in vector graphics, it's just
figured that a "graphics library" starts getting
involved with, for example, rendering fonts and bitmaps
on the screen, it was for the libwy guy.

The libwy guy's and excuse me if I get that wrong,
I've enjoyed his posts about portability and design
and these kinds of things, then for example the ideas
about language profiles, of C++, like when to use what
features, vis-a-vis "really vanilla C++", it's meant to amuse.

Dealing with graphics is like for a buffer, with the
"stride stripe striqe stribe" sort of result the usual
idea of a 2-D array in a 1-D array, then drawing primitives
is a key things, then, for text, is about rendering fonts.

Synthetic-natural hybrid coding?
