Timeline: Use QRgb and a lookup table for colors
It makes no sense to return a QColor as the only things we are using
are the red, green, and blue components. Furthermore, colorFromHue()
can only generate 360 different colors which we can easily cache
instead of recalculating them on each request.
This significantly reduces the time it takes to update the timeline
render nodes.
