robb, now I kinda want to try all kinds of weird stuff with it (instead of something actually useful, like refactoring Smithereen). Especially since I figured out how to apply shaders to things behind the view containing the shader about a month ago. Pretty sure no one at Google thought of this, but it works by drawing the view hierarchy you want to put through a shader into a RenderNode (a second time, in addition to it drawing itself normally where it belongs), and then applying the shader or RenderEffect to that. Maybe I should write somewhere about it. The Android developer community seems to be obsessed with various Kotlin crap instead of trying these new APIs out.
