Sorry, I should have done that, I do tend to fix stuff I find while
coding and neglect splitting up afterwards. Bad me.

Ah, good. At the moment, it's still imlib2 only though. Not great
but will do for now. Cairo/Pango will be needed if/when I add my
rendering lib, but I'm just starting on it, so imlib2 it will be for the
near future.

If you have any comments/concerns about the Kate code, feel free
to comment. Especially on the Javascript API side (never done any
of this before).

will try this.

Two hunks, the first one to initialize the mouse callback pointer
to NULL, and the second one to test for NULL before actually using it:

Well, not really, more like only useful for the new kate test functions:
the keypress routine would be called for every keypress, but all
existing test routines would expect numbers in the input box, and no
numbers were hotkeys for any function, so nothing would get done.
Since I added a function (to see the font to use) that expects input
with other characters than numbers, some test functions would be

However, looking at the patch, the input_focus variable isn't used
by the Kate UI. Were you talking about something else ?

Thanks for your time.
