* border options define what values are set for these extra rows and columns
*
* Assume that the three rows of right edge of the image looks like this:
* .. 3 2 1
* .. 6 5 4
* .. 9 8 7
*
* BOUNDARY_OPTION_CLAMP : the extra pixels are set to the pixel value of the boundary pixel
* This option makes it seem as if it were:
* .. 3 2 1| 1 1 1 ..
* .. 6 5 4| 4 4 4 ..
* .. 9 8 7| 7 7 7 ..
*
* BOUNDARY_OPTION_MIRROR : the input image is mirrored at the boundary.
* This option makes it seem as if it were:
* .. 3 2 1| 1 2 3 ..
* .. 6 5 4| 4 5 6 ..
* .. 9 8 7| 7 8 9 ..
*
* BOUNDARY_OPTION_ZERO_PADDING : the extra pixels are simply set to 0
* This option makes it seem as if it were:
* .. 3 2 1| 0 0 0 ..
* .. 6 5 4| 0 0 0 ..
* .. 9 8 7| 0 0 0 ..
*
* Note that the input image is not actually extended in size. Instead, based on these options,
* the convolution is performed differently at the border pixels.
