Brian G reported a new bug.

Summary
-------

Fonts not correctly displayed - ongoing

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : Development Environment


Description
-----------

I am using the same font for for my system and Gambas.

Gambas seems to be the only application which incorrectly renders the fonts.

See attached image of the way that the help screen is rendered.

This seems to be an ongoing issue, Do we actually have to test the hundreds
of fonts just to find a reliable font that works across the multiple platforms that Gambas supports
to be confident that our apps look the same on each platform?

I understand the complexity and difficulty involved in scaling and rendering fonts.

I really think that Gambas is an incredible achievement, and that you are truly brilliant.
And I love the innovations and progress you have achieved over the years.

But maybe some time could be spent with the trivia around the fonts and scaling.

Maybe some tests added?

Thanks for the Work you do, truly appreciated.
