* For the first pass, tile composition for a given TiledImage is always done using a canvas with a WebGL context.
* This allows tiles to be stitched together without seams or artifacts, without requiring a tile source with overlap. If overlap is present,
* overlapping pixels are discarded. The second pass copies all pixel data from the WebGL context onto an output canvas
* with a Context2d context. This allows appliations to have access to pixel data and other functionality provided by
* with a Context2d context. This allows applications to have access to pixel data and other functionality provided by
* Context2d, regardless of whether the CanvasDrawer or the WebGLDrawer is used. Certain options, including compositeOperation,
* clip, croppingPolygons, and debugMode are implemented using Context2d operations; in these scenarios, each TiledImage is
* drawn onto the output canvas immediately after the tile composition step (pass 1). Otherwise, for efficiency, all TiledImages
