13 * - FIX wrap... long lines that don't fit are not char wrapped yet.
14 * - hrm... something to do with already having tbs...
15 * - selection code... selects can be funny if it crosses over. use rect?
16 *- also inspect behaviour for WACenter and WARight
17 * - FIX: graphix blocks MUST be skipped if monoFont even though they exist!
18 * - check if support for Horizontal Scroll is complete
19 * - assess danger of destroying widgets whose actions link to other pages
20 * - Tabs now are simply replaced by 4 spaces...
21 * - redo blink code to reduce paint event... use pixmap buffer...
22 * - add paragraph support (full) and '\n' code in getStream..
