not too hard at all.. highest depth based on API is very simply.

*sigh*.. of course, i have specified that the maximum i am interested
in is 8 bit display.. if a device comes out with 24 bit displays, and
i want to use it - i will probably release a new version, and hence i
would update the depthsToTry[] array.
cheers.
