ANGLE FOLLOW for labels doesn't handle short strings properly

Description

I have noticed that using ANGLE FOLLOW for labels along lines when the text is 3 or fewer characters long leads to incorrect character orientation.

This is a known bug (see #2020) that I hope to fix before 5.0 final. The path following code is a bit hard to understand though which is why it's taking so long. The problem has to do with the smoothing kernel that is being applied.

#2221 is also the same thing...

Actually #2221 is a duplicate of #2020. This one is specific to 3 or two characters. They are different problems and look differently to users.

I've tested the problem thoroughly and I can confirm that it is indeed specific to 3 or fewer characters. If I pad the beginning of the string with spaces so that there are at least 4 characters the labels follow the line properly.
