Remove opengl dependency from oscilloscope demos....
Remove opengl dependency from oscilloscope demos. These demos do not actually use opengl for anything, so no need for the dependency. This dependency also breaks the demos in android. Change-Id: I4da2a83f11fddd416034821d233f0543ee0900ed Reviewed-by: Mika Salmela <mika.salmela@digia.com>
