The text char is a bit small shown in the grid(wxWidgets + Windows)

I just built the project under wx library on Windows, see the screen shot below:

[asmwarrior]

diff --git a/src/Wx/wxAsciiArt.h b/src/Wx/wxAsciiArt.h
index 69559e7..56f3bb0 100644
--- a/src/Wx/wxAsciiArt.h

-	static constexpr int FONTSIZE = CELLSIZE - 4;
+	static constexpr int FONTSIZE = CELLSIZE;
 
 	wxAsciiArt();
 	wxAsciiArt(wxWindow *parent);

This way, the font can be a little bigger. See below screen shot:

The minor issue is that the base line is a bit low, so the character g is a bit low.

One suggestion, I think the "cell" in the grid should not be a unit square. I mean it could be a bit higher.

If you ever see a freeware named ascii art studio, see here: ASCII Art Studio (Freeware) | www.torchsoft.com you can see its cell is much higher, see the image below:
