Basic pass at histogram. Uses a power based scale compared against the total pixel count. Probably needs a UI toggle to flip lines on and off as the text and lines in OpenGL are a large cycles sucker. Could be likely much faster when migrated to a geometry shader approach. Uses the scaled viewport resolution to increase performance as much as possible.
