Canvas:getPixel

Available since LÖVE 0.9.0 and removed in LÖVE 0.10.0
Use Canvas:newImageData instead.

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.)
