Summary

0001481: [BUG][Balloon] BalloonCanvas not rendering text

Description

Michael Latta <lattam@mac.com>:

"Text is not being rendered for any BalloonCanvas with a transformation.
When I place a StringMorph inside a TransformationMorph subclass that
uses a balloon canvas it does not render. When I look at the code
involved the following two methods stand out.

BalloonCanvas>>drawString:from:to:in:font:color:
BalloonCanvas>>paragraph:bounds:color:

Both call ifNoTransformWithIn: and only attempt to render if it returns
true.

I imagine this is an issue with the use of bitmap fonts, it should be
possible to scale true type fonts. It would be nice however to at
least make an attempt to locate a suitable font. The current code
results in just blank space.

It is getting to the bitblt, but nothing shows. I suspect a clipping issue with the use of TransformationMorph. The bounding box is centered on 0, rather than being all positive as in the normal morphic cases. I am still looking into this, but as usual if someone has knowledge of this let me know. Michael"

But it is not dealing with scaling yet. I should have a fix pretty soon for this with TT fonts at least. Michael"
