Moravec interest points locator.

Parameters

rasterData	The loaded raster data.
maskRasterDataPtr	The loaded mask raster data pointer (or zero if no mask is avaliable).
moravecWindowWidth	Moravec window width.
maxInterestPoints	The maximum number of interest points to find over raster 1.
enableMultiThread	Enable/disable multi-thread.
interestPoints	The found interest points (coords related to rasterData lines/cols).

Note: InterestPointT::m_feature1 will be sum of differences between the Moravec filter response of each pixel and its neighborhoods (always a positive value).

Returns: true if ok, false on errors.
