tilda fails to update its window after losing focus

[gijsbers]

If I run this command in a tilda window:

   while :; do date ; sleep 1; done

Then tilda will stop updating its window after I move my mouse to some other window, because I have focus follows mouse. Only after I move the mouse pointer back into the tilda window does tilda update its window again. I much prefer if tilda would just always update its window, regardless whether it has input focus or not.

Compilation of tilda 1.6-alpha gives the following warnings, due to missing include statements:
