0030316: Font: font_add_sprite_ext() separator calculation seems to be +1 in 2.2.1 compared to 2.2.0 and older
Description
When adding a new font in-game via font_add_sprite_ext() you can see the separator calculation seems to be +1 in 2.2.1 compared to 2.2.0 and older. So, e.g., for a separator of 0 you still have padding.
You can see this in the attached screenshots and sample.
Steps To Reproduce
1. Run the attached sample for Windows/HTML5.
2. Observe it looks like the 221 screenshot, not the 220.
