AGOS: SIMON1: displayBoxStars() uses wrong color for Amiga CD32 version

[eriktorbjorn]

I noticed that when using the F10 key to display hotspots in the CD32 version of Simon the Sorcerer 1, it did not use white to draw the hotspot markers. In the DOS verion - and in the Amiga demo - it does.

The color is hard-coded in AGOSEngine::displayBoxStars(), and I guess the CD32 version uses a different palette?

I'm very fuzzy on how colors work, but it seems the palette is subdivided into one 32-color palette (palette number 0) and fourteen 16-color palettes, with palette fifteen being used for inventory object. So that one presumably remains constant throughout the game. It doesn't seem to have any pure white color in it though.

Of course, we could change the function to look up the closest it has to white and use that throughout.
