Some truetype fonts have good manual hinting.
Ignoring hinting makes the font render badly on low resolution screens.
This commit only disables the freetype autohinter, and allows hinting.
Remote whitespace at the ends of lines.
Remove blank lines from the ends of files.
Change modes on source files so that they
are not executable.

If $font is not set, the default font is constructed from
font data linked into every libdraw binary. That process
was different from the usual openfont code, and so it was
not hidpi-aware, resulting in very tiny fonts out of the box
on hidpi systems, until users set $font.
Fix this by using openfont to construct the default font,
by recognizing the name *default* when looking for
font and subfont file contents. Then all the hidpi scaling
applies automatically.
As a side effect, the concept of a 'default subfont' is gone,
as are display->defaultsubfont, getdefont, and memgetdefont.
This makes fontsrv use the PostScript font names on X11.
The PostScript font names contains only alphanumeric and
hyphens. This allows us to use the Font command in acme.
It also matches the font names used by fontsrv on macOS,
which has been using PostScript font names.
macOS Mojave version 10.14 starts to disable font smoothing.
We disable font smoothing for OSX_VERSION >= 101400 to match the
system default font rendering.
It also makes the font rendering on macOS similar to that on X11.
* Avoid allocating empty images by adding 1 to width/height. This was
crashing fontsrv. The total width of the subfont image can be zero
even if the characters are present in the font. For example, all the
characters in x0300.bit (part of "Combining Diacritical Marks" Unicode
block) have zero width.
* Make sure U+0000 is always present in the font, otherwise libdraw
complains with: "stringwidth: bad character set for rune 0x0000 in ..."
* Use the same fallback glyph (pjw face) as OS X. This also fixes a bug
where advance was set to the total width of subfont instead of the
character.
Update #125 (most likely fixes the crash if in X11)

For some fonts, using box-drawing characters in the representative
text for computing the line height results in it being uncomfortably
high. Replace them with accented capitals and tall lower-case letters
which lead to a more conservative increase in the line height.
Fixes#162.
Double the width returned by CTFontGetBoundingBox when drawing.
Add box drawing characters for determining the line height.
Call freememimage(1) for the character memimage.
Fixes#18.
Fixes#120.
Fixes#146.
Makes loading faster, and makes larger sizes not too wide.

This gets us font fallback for free and avoids use of a
deprecated API that might go away some day.
