opacity and blur slider slow and incremental with 0.47 / smooth with 0.46

[marcel]

When shifting the opacity and blur slider in the Fill and Stroke Dialog (shift + control + F)
the objects properties change incrementally not smoothly.

With 0.46 everything is fine. The sliders run very smooth.

Inkscape 0.47 r22583, built Nov 21 2009

Windows XP and Windows 7

Inkscape 0.47 now behaves differently, and the sliders no longer works step by step but adds a delay (half a second or so after the mouse stop) before catching the event. I think this is the a wanted change (improved performances when blurring on a big drawing), but I find no trace of it in the release notes and LP. Could someone confirm?

@JazzyNico - could it be related to this?

Revision 7446 by buliabyak, 2009-03-09 00:38:46
switch opacity and blur sliders to delayed update, which makes them much more resposive and easier to handle; also, remove the old workaround for gtk crash which is no more, allowing interruptibility and thus also improving responsiveness

'old workaround for gtk crash' seems to refer to

@~suv, yes, that's what I was looking for, thanks!
