            Description

            The file in question has an interesting gradient effect for the background which is composed of two very large images (4k x 4k). With a 2GB heap we can decode these two images but when we create the resultant image we blow the stack.

            We should be able to get around this issue but not creating the resultant issue or down scaling the images earlier on during the render cycle.
