- Now using text_update_common() for the new text update API in addition to the graphical text snapshot feature. - Drawing to snapshot buffer moved to new method draw_char_common(). - A gui using the new text update API only needs to implement the new method draw_char(). The method set_font() is optional and it can be used to update font bitmaps / pixmaps. - Modified the RFB gui to use the new API. Now the VGA features split screen and h/v pel panning are supported by the RFB gui. The legacy text_update() method is now empty but it must be present for compatiblity. - TODO: Implement new API in some other guis to reduce code duplication.
