filter_kernels: fix quadric window
3909e4cdfcb9 seems to have replaced this 0.5 constant by 0.75, using its
presence in glumpy as justification.
0.75 is clearly a bug in glumpy, as its own source code doesn't even
match the comment immediately above it. Every other implementation of
this window I could find uses 0.5, including e.g. ImageMagick.
