| This function is not supported in earlier versions. |
Gets the pixel at the specified position from a Canvas.
Valid x and y values start at 0 and go up to canvas width and height minus 1.
| This function can be very slow: it can cause the CPU to wait for the GPU to finish all the work currently in its queue, which can be a whole frame's worth (or more.) |
