Michael Drake aa380ed47a More scaled rendering improvements. Partial redraws of scaled textareas can't work atm, since neither the textarea nor content is aware of scale. 2014-01-21 14:37:46 +00:00

Michael Drake 2ad0d23915 Start reducing unnecessary redraws: when only start OR end of selection has changed, only redraw the lines affected. (Reduces redraw of vertical regions only. Still redraw full width for changed lines.) 2013-03-19 16:22:24 +00:00
Michael Drake 8d0c1f9207 Loads of changes including fixes, new functionality, and optimisation.
+ Refactor internals to be byte, rather than character based.
    + Don't need to hammer utf8_* functions everywhere
    + Optimises:
        + Redraw (lots)
        + Editing (insertion, replacement, removal)
        + Caret placement
        + Selection
+ Early avoid of zero length autoscroll during selection drag.
+ Optimised redraw to avoid nsfont_width when:
    + There's no selection at all.
    + We're on last part of line, and it's unselected.
+ Implemented WORD_LEFT and WORD_RIGHT keys (shift + cursor left/right)
+ Fixed UP and DOWN (cursor up/down) keys to handle non-monospace fonts.
  (Now based on 'x' offset on line, rather than character offset on line.)
+ Fixed PAGE_UP and PAGE_DOWN to scroll without moving the caret.
+ Fixed redraw bug in text selection edge case.
+ Changed textarea_replace_text and textarea_insert_text to return
  a byte delta for caret position changes.
+ Coordinate to text offset function handles global and viewport coords.
+ Many small improvements and tidying.
