If @mark_name is %NULL, the mark is anonymous; otherwise, the mark
can be retrieved by name using [method@Gtk.TextBuffer.get_mark].
If a mark has left gravity, and text is inserted at the mark’s
current location, the mark will be moved to the left of the
newly-inserted text. If the mark has right gravity
(@left_gravity = %FALSE), the mark will end up on the right of
newly-inserted text. The standard left-to-right cursor is a mark
with right gravity (when you type, the cursor stays on the right
side of the text you’re typing).
The caller of this function does not own a
reference to the returned GtkTextMark, so you can ignore the
return value if you like. Marks are owned by the buffer and go
away when the buffer does.
Emits the [signal@Gtk.TextBuffer::mark-set] signal as notification
of the mark's initial placement.
Creates a mark at position @where.
