Hi guys, I've been messing with the blur tool today and noticed a few behavioural optimisations we could do to the slider to cut back on bloating our files. the slider should lock to Increments. for example : 0.25 0.50 1.00 2.50 5.00 7.50 10.00 20.00 the user is still allowed to specify an arbitary value but it may be useful to handle filters in a similar way as we do gradient definitions. Create the <filter> def for the stddeviation when it has been set and link to that same <filter> for all future blurs if the same value. The locking of the slider comes into place because it makes the default user behaviour more optimised when only casually playing with blur settings. I guess we should think about htis . oh, also attached is a quick example i made today to show an airbrushed style effect using blurs and gradients
