Summary	0001564: Regression from 2.2.*: Image disappears if rendered outside of screen with clipping and opacity less than 1
Description	An image in canvas isn't visible when following conditions are met: 1) it's opacity is < 1 2) the parent canvas Clip height is such that canvas goes beyond screen bottom edge 3) image TranslateY is such that image's bottom edge is outside the screen This used to work in a past version of Noesis (OK on 2.2.1 - confirmed, not sure about the other) See sample minimal project to reproduce
Steps To Reproduce	Open attached project, open SampleScene Run in Editor -> all OK In CopyPastePage.xaml, uncomment the debug line (and comment the one below): <!-- ATTENTION: to reproduce image disappearing change opacity to < 1, like 0.6 --> <!-- <Canvas IsHitTestVisible="False" Visibility="Visible" x:Name="panelClone" Opacity="0.6"> --> <Canvas IsHitTestVisible="False" Visibility="Visible" x:Name="panelClone" Opacity="1"> Run again Expected: all OK Actual: image not visible Blocker for us, since we are working on image painting program and can't rotate the canvas anymore - if the user rotates it and an edge exits the screen, the whole canvas disappears.
