resultossimDpt to initialize with requested decimation.
Note
Initialized "result" with the decimation factor for the passed in resLevel. Most of the time the returned factor is a square decimation along x and y indicated by result.x and .y = 1.0/(resLevel^2) where ^ means rasing to the power of. If the resLevel is 1 then the return decimation .5, .5. this is not the decimation to each resolution level but the total decimation from res level 0. So if resLevel is 2 then the return is .25, .25.
Derived classes should override if the decimation is anything other than a power of two change in each direction per res level.

Returns
Returns true on success, false on error.
Note
This method relies on the data member ossimImageData::theImageFile being set. Callers should do a "setFilename" prior to calling this method or use the ossimImageHandler::open that takes a file name and an entry index.
