* Menu/KeyValuePage/ReaderGoTo: Unify the dialogs. (Generally, "Enter page number" as title, and "Go to page" as OK button).
* Allow *tapping* on pagination buttons, too. Added spacers around the text to accommodate for that.
* Disable input handlers when <= 1 pages, while still printing the label in black.
* Always display both the label and the chevrons, even on single page content. (Menu being an exception, because it can handle showing no content at all, in which case we hide the chevrons).
* KVP: Tweak the pagination buttons layout in order to have consistent centering, regardless of whether the return arrow is enabled or not. (Also, match Menu's layout, more or less).
* Menu: Minor layout tweaks to follow the KVP tweaks above. Fixes, among possibly other things, buttons in (non-FM) "List" menus overlapping the final entry (e.g., OPDS), and popout menus with a border being misaligned (e.g., Calibre, Find a file).
* CalendarView: Minor layout tweaks to follow the KVP tweaks. Ensures the pagination buttons are laid out in the same way as everywhere else (they used to be a wee bit higher).
- 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.
