Introduced a new parameter for ctk_draw_window() that indicates if drawing the window borders is required.

This allows to avoid unnecessary drawing of window borders on calls to ctk_window_redraw() which happen often in the web browser.

Several ctk_draw_window() implementaions don't make use of the new parameter yet.
