[BlackBerry] Propagate GraphicsLayer::boundsOrigin down to the platform layers

[Antonio Gomes]

PR #188657

This property is being used to translate hardware accelerated "Layers", for
fast scrolling (primarily blocks, i.e. divs and friends).

We need to support it therefore.

Not familiar with InRegion scroller. But this patch looks good to me

I think this is dead code, since you started using LayerOverride::setBoundsOrigin() instead. The only reason to place a setter in this block is if you want to be able to run a LayerAnimation on that property, or if you expose boundsOrigin in the WebOverlay API.

True. Will clean up...
