Both widgets now make use of their base class's scrolling timer and
now always accept drag selection updates on mousemove_event().
This guarantees much snappier feeling selections when actively moving
the mouse.
Selections are always normalized when saving undo commands.
The restore_selection() function reverses this process so
negatively sized selections (created right-to-left) continue
to resize correctly with the keyboard when restored.
Previously the widget used a very rough estimate for visible glyphs
based on viewport and glyph areas. Now it simply figures rows times
columns with a two row overdraw to accommodate fractional glyphs
on either end of visible content. For KaticaRegular10, this ends up
reducing unnecessary glyph iterations during painting by about 30%.
Fixes a slightly oversized content rect and erroneous glyph outer
rect values. Increases glyph rect padding to guarantee at least 1px
between the focus rect and glyph.
This is a bogus size as the map must always have at least 1 glyph
selected, and it was causing occasional desync between selection
contents and the focused glyph when manipulating selections with
the keyboard.
And TRY early during initialization in FontEditor to leave the app
in a valid state on error. Fixes OOM crashes when cloning the original
font for highlight modifications.
This makes modifications in FontEditor more visible, both so you know
what you've changed, and for taking a handy "here's what's changed"
screenshot for a font PR. :^)
The background color for new glyphs is green, modified glyphs is blue,
and deleted glyphs is red. The changes persist until you load a new
font file, so you can continue saving your work as you go and still be
able to take a convenient screenshot at the end.
I didn't feel like this one use was enough to add 3 new color roles to
themes, so to make this look decent on dark themes, it detects if the
theme is marked as dark, and uses darker colors for the highlights
which look nice with a light text color.
GlyphMapWidget now reports context menu requests when secondary
clicking the map. This also adds a new Select All action and updates
the Copy Character action to work on multi-glyph selections. Glyph
navigation actions have been moved to a separate Go menu, as is
common in other apps.
Previously, if it was displaying N glyphs per line, then you changed
font to one that was a drastically different size, it would continue to
display N glyphs per line until you resized the window. Now, we
immediately recalculate how many to show, so that they fill the
available width. :^)
