Fwd: Convolution

[Boudewijn Rempt]

I've got blur working now; it has more or less the same problem as the old 
convolution painter except it now has it on all four sides. The problem is 
that the default pixel of a paint device is invisble black. The black is 
picked up when the matrix tries to read beyond the edge of the paint device.

Anyway, my code still doesn't work when there are negative values in the 
matrix -- the results are very electric, but not good enough.
