12 /* TODO:
13 * - verify what happens with XK_return in insertTextInt...
14 * - selection code... selects can be funny if it crosses over. use rect?
15 * - also inspect behaviour for WACenter and WARight
16 * - what if a widget grabs the click... howto say: "pressed me"?
17 * note that WMCreateEventHandler takes one data, but need widget & tPtr
18 * - FIX: graphix blocks MUST be skipped if monoFont even though they exist!
19 * - check if support for Horizontal Scroll is complete
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..
