Yet another patch..

This one is a case of "add code to gain speed".

By adding a special case handling of "kernel being tested 
is within the borders of the image",you gain speed by not
performing a conditional in the loop, which allows for 
gcc 4.1's autovec engine to change your loop to a series 
of SSE2 instructions.

Get all that? :)

Anyways, this brings the speed down to ~1.3 on my machine.

the 70-* and 80-* patches have equivilents for convolutions
two and four, i'm just not getting it quite right yet...

I'm also attaching my testing program, so that others can
check my work.
