Use a hillshade renderer on a raster.
How to use the sample
Configure the options for rendering, then tap 'Apply hillshade'.
How it works
The parameters provided by the user are passed to HillshadeRender at instantiation: new HillshadeRenderer(mAltitude, mAzimuth, mZFactor, mSlopeType, mPixelSizeFactor, mPixelSizePower, mOutputBitDepth); which returns a RasterRenderer. The RasterRenderer is then added to the RasterLayer.
