Subject: [PATCH 1/2] pixops: Chane variable type

n_weights is used to do overflow checks. So by reducing the size to 32
bits signed we overflow earlier. This is necessary because further down
the code lots of code uses int variables to iterate over this variable
and we don't want those to overflow.

The correct fix would be to make all those variables gsize too, but
that's way more invasive and requires different checks in different
places so I'm not gonna do that now.
And as long as scale factors are not expected to reach G_MAXINT it's not
really necessary to do this change anyway.
