imageFilter

It my be interesting to apply some filters to the image, to remove dust, etc. The functions of this module will get the image and apply the filter to it.

Prototype is

int gocr_imageFilterFunction ( gocrImage *image, void *v );
You can work freely with the image, and apply any filters you desire; remember that modules that were not written by you may be used too, so do not apply a filter that changes the image data (gradient, laplacian, Fourier transform, etc). As a special note, do not create (complete) copies of the data, since it's likely to be big (expect a few megabytes for the image size).

todo: document application of filters to blocks of data, which may be transformations, etc.
