I can't tell you how to *easily* do it in iTools but you'll be looking
to change the text objects RENDER_METHOD to 1 (triangles). The default
method for IDLgrText from 6.0 on has been to render text as a bitmap
texture mapped on a polygon. This "texture" method allows for
anti-aliasing of the font which is what is causing the "fuzziness".
You may have some trouble though since the iTools (seem to) rely on the
FILL_BACKGROUND and FILL_COLOR properties of IDLgrText and these are
only available when rendering as a texture. But maybe the iTools are
coded to handle both methods... I really haven't poked around inside
them in a long time.
Josh does bring up a good point though. The anti-aliasing is pretty
soft. Is there some consensus on this? Maybe there should be a feature
request to add a property to IDLgrText which would control the
anti-aliasing. Something along the lines of "none" "crisp" "strong"
"soft" similar to photoshop's handling of this. I know, I know. We're
*never* satisfied.
