GtkSourceDrawSpacesFlags determine what kind of spaces whould be drawn. If none
of GTK_SOURCE_DRAW_SPACES_LEADING, GTK_SOURCE_DRAW_SPACES_TEXT or
GTK_SOURCE_DRAW_SPACES_TRAILING is specified, whitespaces at any position in
the line will be drawn (i.e. it has the same effect as specifying all of them).
GTK_SOURCE_DRAW_SPACES_SPACE
whether the space character should be drawn.
GTK_SOURCE_DRAW_SPACES_TAB
whether the tab character should be drawn.
GTK_SOURCE_DRAW_SPACES_NEWLINE
whether the line breaks should be drawn.
GTK_SOURCE_DRAW_SPACES_NBSP
whether the non-breaking whitespaces should be drawn.
GTK_SOURCE_DRAW_SPACES_LEADING
whether leading whitespaces should be drawn.
GTK_SOURCE_DRAW_SPACES_TEXT
whether whitespaces inside text should be drawn.
GTK_SOURCE_DRAW_SPACES_TRAILING
whether trailing whitespaces should be drawn.
GTK_SOURCE_DRAW_SPACES_ALL
wheter all kind of spaces should be drawn.
