Creates a source mark in the buffer of category category. A source mark is
a GtkTextMark but organised into categories. Depending on the category
a pixbuf can be specified that will be displayed along the line of the mark.
Like a GtkTextMark, a GtkSourceMark can be anonymous if the
passed name is NULL. Also, the buffer owns the marks so you
shouldn't unreference it.
Marks always have left gravity and are moved to the beginning of
the line when the user deletes the line they were in.
Typical uses for a source mark are bookmarks, breakpoints, current
executing instruction indication in a source file, etc..
Since 2.2
