*	Make bubbles use one background picture that is the size of the display ↵	Marianne Arnold	2007-09-28
	instead of combining a 'left' and sometimes a 'right' bmp. This way it's clearer how the background is generated and adapting to new display sizes should be easier. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14893 a1c6a512-1295-4272-9138-f99709370657
