#299 Call Tip popup cutting off top of Japanese characters

[Forest]

The Call Tip popup window is cutting off the top of
Japanese characters. This makes many Japanese
characters unreadable.

I have made a fix for this and it looks good in both
Japanese and English.

2 Fixes in CallTip.cxx:

------------------------------------------------------------
CallTip::PaintContents
------------------------------------------------------------
line 138:
// To make a nice small call tip window, it is only
sized to fit most normal characters without accents
int ascent = surfaceWindow->Ascent(font) /*-
surfaceWindow->InternalLeading(font)*/;

*** Don't subtract the InternalLeading

------------------------------------------------------------
CallTip::CallTipStart
------------------------------------------------------------
line 253:

// Extra line for border and an empty line at top and

bottom
int height = lineHeight * numLines /*-
surfaceMeasure->InternalLeading(font)*/ + 2 + 2;

*** Don't subtract the InternalLeading

I think that this adds too much space for the main use case
which is for ASCII function parameters. A modification that
looked at the actual text would be better.

I attached a screen shot of the space used with the fix for
ASCII characters in CallTip_ENU.JPG. It looks good to me.

There are 2 pixels of extra space at the top making it look
unbalanced.

Yeah, you are right. I'm sure there is a more robust fix,
but this fix is better than not having unreadable Japanese.
(at least for me) I will do my own build until this is
addressed in a public release.

Thanks for the great edit control.
