Noticed while working on #134814 that `BLF_width_to_rstrlen()` would
give one character too much to put into the available space, resulting
in a visual overflow or clipped text when BLF clipping is enabled.
I think the issue was hidden by the code from 9c09998530, which would
remove further characters until the string actually fits. I'm proposing
to disable that code for now, hoping that this properly fixes the issue.
`BLF_width_to_rstrlen()`/`blf_font_width_to_rstrlen()` are supposed to
find the largest part from the end of a string that fits into a given
width. It would iterate the string from the back until a character
doesn't fit into the width anymore. However, it would return the
index of that character, the one that doesn't fit anymore, instead of
the last character known to fit.
