nick black 63e32a94c0 Sextants: fix arithmetic mistake that broke 🬓, 🬦, 🬧 
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:

Kovid Goyal ef596f6a8b Distribute extra pixels among all eight-blocks rather than adding them all to the last block 
Makes one block stand out less, every block is now at most a pixel in
size different from every other block. Fixes #3097

Kovid Goyal 80e39212b8 Linux: Fix automatic detection of bold/italic faces for fonts such as IBM Plex Mono and have the regular face with a full name that is the same as the family name 
Fixes #2951

Kovid Goyal 817f0997cf Fix one pixel mis-alignment of rounded corners when either the cell dimensions or the thickness of the line is an odd number of pixels 
The control points of the Bezier curve and the spread due to thickness
must match up with the values used to draw straight lines. In order to
ensure that, one calculates them before upscaling by the super sampling
factor, rather than after. Fixes #2907
 2020-08-10 17:28:08 +05:30
Kovid Goyal 533688a67a Implement support for box drawing rounded-corners characters 
Fixes #2240
 2020-07-12 12:35:52 +05:30
Kovid Goyal 4309e2371d Simplify code by using supersampling for diagonal lines as well 
Wu antialiasing obviously performs better but since characters are
rendered only once and are very small in pixel size, performance is
irrelevant here.

Kovid Goyal 145ec86d3b Forgot to add supersampling to rendering of filled D 2020-07-11 23:10:43 +05:30

Fixes #2844

Kovid Goyal 8b2fb105d0 Fix #2735 2020-06-05 19:24:40 +05:30
Kovid Goyal 362e4266bb Better coalescing of multiple symbol_maps 
When specifying multiple symbol_map values in kitty.conf later ones
should override conflicting previous ones. Fixes #2662

Trygve Aaberge 931e91f1a7 Read strikethrough info from font when using FreeType 
This reads the strikethrough position and thickness from the font so it
is rendered correctly.

This is only implemented for FreeType, not Core Text, because I didn't
find any way to get the info from Core Text, and I don't have a Mac to
test it on either. When using Core Text or when the font doesn't provide
the info, the same approximation as before is used.
