[CHARMAP_NEW]

Browse source 
- Allow the dialog to be resized, which in turn will grow / shrink the grid view and the fonts inside it. This means users can make the grid larger if they don't have their glasses on or want to see all the fonts in more detail. We no longer need a large font window popping out from the grid when you click on a cell (which I was never a fan of). 
- Don't allow scrolling previous to row 0 or after the last row
