Clarify that RFC1950-style zlib-wrapped deflate (as opposed
to RFC1951-style raw deflate) payloads are sent in the
graphics protocol, and that base64 encoding follows
compression (implied by remarks elsewhere, but go ahead and
make it explicit here).
The scheme used in draw_sextant works well enough, but the
feed was broken. 21 and 42 need to be skipped, not 20 and
40. Without this change, the following glyphs are broken:
U+1FB13 BLOCK SEXTANT-35 🬓 renders as LEFT HALF
U+1FB26 BLOCK SEXTANT-46 🬦 renders as SEXTANT-146
U+1FB27 BLOCK SEXTANT-146 🬧 renders as RIGHT HALF
With this change, the entirety of the sextant block works
correctly. Found debugging the Notcurses sextant blitter:
