Cursor positions are (unsurprisingly) positions where the
cursor can appear. Perhaps surprisingly, there may not be
a cursor position between all characters. The most common
example for European languages would be a carriage return/newline
sequence.
For some Unicode characters, the equivalent of say the letter “a”
with an accent mark will be represented as two characters, first
the letter then a "combining mark" that causes the accent to be
rendered; so the cursor can’t go between those two characters.
See also the [struct@Pango.LogAttr] struct and the [func@Pango.break]
function.
Moves @iter forward by a single cursor position.
