Memory leaks in gridview

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

Dear Gambas team,

I have a few problems with the gridview control.
As soon as I change the font size or bold properties the memory used by the program is increasing.
I've got the same effect with the RichText property when I use the <B> tag (as an example)

I also noticed a smaller memory leaks with the cell background color change.

Attached, you will find 3 sample programs to demonstrate that.

Run it and check the memory used in the task manager.

You will notice that for the background color, the leak is coming quite slowly. It's less important but it's there.

I use Gambas V3.12.2 on Debian Buster

Thanks for your help
