More scaled rendering improvements. Partial redraws of scaled textareas can't work atm, since neither the textarea nor content is aware of scale.

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.)

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.
