-- Work out why XFreeFont in font.cpp produces a segv. This is
- currently commented out, which presumably causes a memory leak.
-
-- Colour setting in widgets (almost done). Should scrollbars take
- on the background colour? Not right for e.g. wxScrolledWindows,
- so maybe have wxSystemSettings value for scrollbar colour, and/or
- ability to set scrollbar colour independently.
-
-- Make wxDialog OnPaint work.
-
-- Optimize wxWindow OnPaint, clipping the damaged
- region.
-
-- Implementation of OnEraseBackground. How? Call OnEraseBackground
- just before OnPaint? Will duplicate Xlib's own erase of the background.
- However, this is usually OK, because the default wxWindow::OnEraseBackground
- can do nothing (SetBackgroundColour will make the background look OK).
- And if a custom OnEraseBackground uses the same colour as the window
- background, no flicker will be seen. If it does something else, such as
- painting a tiled bitmap, then a slight flicker might be seen unless
- X can be persuaded not to repaint the window background by default.
