[PD] Font weirdness with 0.43test

Sure...  here:

#N canvas 359 131 405 427 10;
#X msg 98 55 \; line 1 \; line 2 \; line 3 \; line 4 \; line 5 \; line
6 \; line 7 \; line 8 \; line 9 \; line 10 \; line 11 \; line 12 \;
line 13 \; line 14 \; line 15 \; line 16 \; line 17 \; line 18 \; line
19 \; line 20;

On my machine the text box is several (20?) pixels too tall and to select
the bottom line of text you have to click way below it.

I don't see how the thing can be made truly cross-platform unless there's
a way to get text to have a determined size (both vertical and horizontal)
and that seems to be impossible to get to work cross-platform.

The only solution I can think of for getting boxes to have consistent sizes is
to use Mathieu's suggestion and make the box have a standardized size, simply
adding margin when the text font doesn't actually fill it.  (There's have to
be an outline drawn around comments when the patch is unlocked too.)

cheers
Miller
