> This PR aims to address the following issue: JDK-8088198 Exception thrown from snapshot if dimensions are larger than max texture size
> In order to do that, it simply captures snapshots in multiple tiles of maxTextureSize^2 dimensions (or less, as needed), and then recomposes all the tiles into a a single image.
> Other than that, the logic used to do the actual snapshot is unchanged.
> Tests using the existing SnapshotCommon class have been added in a new file named Snapshot3Test under SystemTest/test/javafx/scene.
> These tests pass with the proposed fix, and fail without, throwing " java.lang.IllegalArgumentException: Unrecognized image loader: null"
