- Added two new dialogs - input devices; (GtkInputDialog)
and DeviceStatus - which shows the tool/color for
each device.
- Added device_status_update() call that gets called
whenever the tool/color etc. are changed.
- Added ~/.gimp/devicerc file to store settings
- Code to draw cursor on canvas for non XFree86 XInput
where device can't control cursor and extended input
device simultaneously.
- Changed input handling so that we always use the pointer
position from the device, not from gdk_input_window_get_cursor,
so that motion and cursor position sync.
- Various changes so things work with non-integer coordinates
- Pay attention to pressure and tilt in basic tool support.
- New paint mode PRESSURE that changes the brush based on
the brush pressure
- Left in a few XInput hacks that should be removed, but I no longer
remember what they are.
