Fix a bug where we get drag events outside the window, causing us to try to look up a line with a bogus index

Fix a bug where sometimes a character's code is set to 0 but its complexChar flag is left as YES, leading to an assertion because there is no UTF-8 string with that code

Hide toolbar in fullscreen windows. Save toolbar setting in user prefs. Make sure it is consistent across all windows.

When a top/left/bottom window specifies more rows/cols than fit, try to resize it when the window grows. Remember the 'desired' size of such a window when it is created. Also add a delay before canonicalizing windows after the screen parameters change to work around a bug in osx

Performance improvement--do not allocate a new CharacterRun for each character. Also cache colors in constructRuns.
