Description
Created attachment 328657 rsvg-filter: Use memset instead of a manual for loop
when blurring, we're calling put_column and get_column a lot, these both copy some data around via a manual for loop. Replace that with a simple memcpy(). Also, use memset() to initialize an integer array to 0 instead of a manual loop.
