- Add IconWidget, use it for icons instead of ImageWidget.
Specify icons by name only, look for them (with either
.svg or .png suffixes) in multiple directories (including
koreader/settings/icons/ to allow customizing them).
Don't crash when icon name not found, shown a black
background warning icon instead.
- Don't trust the icons' native sizes: replace
scale_for_dpi=true with width/height=DGENERIC_ICON_SIZE,
so all icons get the same (tunable) size - except in
a few specific use cases.
- Top and bottom menu bars: normalize, and have icons
properly centered in them, extend vertical line
separators up to the edges.
- TOC: adjust expand/collapse icons size to items size
Just by tweaking the SQL queries, and adding an index
on page_stat_data(start_time).
Also, in the hourly histogram, show at least a 1px bar
when there was any reading this hour.
Also adds options to remove statistics for books
with low reading duration (to clean up stats for
books just quickly browsed and not yet read).
Also adds TextWidget:getFontSizeToFitHeight()
even if we ended up not using it.
