[Image Rendering] Be able to change the color of boxes and labels

[marianopeck]

Right now, they are black. We experimented with processResultsAndDrawBoxes and saw that adding something like:

gc setForeground: (image palette nearestPixelValue: (Color red)).

seemed to work. However, the resulting display color is not similar to the one we specified. This is likely related to the palette we are using to send nearestPixelValue:.

Check what the color palette is for it. If it’s really limited, then perhaps it is the nearest color..

Maybe we need to enable full VA RGB palette by reading the rgb.txt? Check private email for this.
