Small tweaks all around to handle UI mirroring: - swap existing symbols like arrows, or use alternative ones - rotate some images, like chevrons and dogear icons - flip some left and right swipe handling - flip some geometry arithmetic like tap on left or right side of page or dict window - use new ProgressWidget:getPercentageFromPosition() instead of geometry arithmetic - BD.wrap() some concatenated string bits, like in reader and menu footers - flip inverse_reading_order when UI is mirrored More specific tweaks: - ReaderGesture: reset some specific gestures when UI direction has changed (tap on top/bottom left/right corners, for bookmarks and FileManager "Plus menu"). - ReaderRolling: show markers on the correct side of page, in single or dual page mode. - KoptOptions: swap left and right icons in Alignment toggle - CheckMark: proper rendering in all 4 mirroring/rtl combinations. - VirtualKeyboard: forbid any mirroring - Move util.getMenuText into Menu.lua
