ImageScanlineBuffer(ImageFormat readFormat, unsigned width, ImageFormat convertSourceFormat);
ImageScanlineBuffer constructor.
ImageScanlineBuffer is used by Image::Decode implementations. Two passes are possible during conversion:
1. Convert from image-file format to convertSourceFormat (optional).
2. Convert to Decode destination format with users copyScanline function.
First step is necessary if raw image-file scanline doesn't match the ImageFormat requested during image creation.
