Hi again,

Well, after a lot of fiddling, I actually made a pretty good amount of
progress. I've added tooltips to BJTs informing you if you overrate them
and what specifications have been overrated.

See screenshot:

Work needs to be done on separating parts of the drawing code from
calculation code, as it's still a big hack. Then applying it to other
components like ICs, capacitors, and resistors. Finally I need to figure
out how to post a patch, because I haven't really kept track of files I
changed. (Though my editor, KDevelop, leaves backup files like 'main.c~'
which is useful in seeing which files have been modified.)

I have made a modification which lets components set their own tooltips.
At the moment these tooltips are all, by default, set to the component
name. I was thinking of adding useful info like power dissipation, charge
in a capacitor, etc. to the tooltips. Any other ideas?
