Previusly a cloned or newly loaded font was moved twice from main to
the constructor and then from constructor to an init routine where it
was finally used. The unmasked font is now moved only once, directly
to initialization, and redundant error checking is discarded.
GlyphBitmaps are considered present if they have a width greater
than zero. This adds a counterpart method for raw (unmasked) glyphs
and makes intent more explicit throughout FontEditor.
The editor now unmasks fonts on load, mapping their glyphs to the
complete unicode character set, and masks them upon saving to
reduce disk space. This is a naive approach in terms of memory
usage and can be improved but whose immediate goal is to allow
editing any glyph without concern for range allocation.
Previously we would loop over all glyphs in the GlyphMap, compute
their rects, and then test to see if the mouse click position was
inside that rect. This is silly since each element in the glyph
map for a particular font is the same size, and we can just do
some coordinate manipulation to get the index directly.

This replaces the glyph width spinbox in the font editor with a
checkbox when editing fixed width fonts that indicates if the
currently selected character's glyph is present in the edited font
(For variable width fonts a non zero width implies presence)
This commit also changes the background color of glyphs in the glyph
map based on the presence of each specific glyph in the font.
Fixes glyphs not updating when loading between fonts at the same
index. Fixes GlyphEditor spinbox inadvertently modifying width
of last selected index.
This makes it easier to work in FontEditor at low resolution.
Previously glyph map resized itself and the parent window to
accomodate fonts, which isn't ideal. Users typically control
window size/position after launch; widgets have to make do.
