previous commit wasn't good, instead tweak existing code

sync with cursor drawing code, reduce confusion.

Merge branch 'master' into temp-text_editor_cursor_api

Merge remote-tracking branch 'refs/remotes/origin/master' into temp-text_editor_cursor_api

forgot to handle tabs in lines properly as well

fix for linenumber offset, was not taken into account before, also missed some y offset because cursor position was at top-left of character

made the y coordinate start at bottom left of the region

take 2 args (line, col) instead of a tuple, matches other similar functions.

rename for consistency

move text-space api func into rna_space_api.c

add BKE_screen_find_area_from_space and call from rna_space code.

also rna correct function flag use.

minor refactor/rename
