scroll-actor: Use :child-transform (4.91 KB, patch)

Description Tomeu Vizoso 2012-10-16 15:13:41 UTC 
It should probably use ::child-transform instead of ::apply-transform for scrolling its contents.

To see why that may be wrong, run with paint-volumes and dump-pick-buffers and see how the paint volumes and pick areas overflow the container allocation.

scroll-actor: Use :child-transform

Instead of using a custom apply_transform(), paint(), and pick()
implementations, we can simply apply a transformation to the children of
a ScrollActor.
