    Nice introduction to CoreGraphics. I am not sure you explained the Matrix flipping.

    For those who did not understand why this step was introduced it is because the coordinate system differs between UIKit and CoreGraphics, which in CoreGraphics is flipped on the Y-axis compared to UIKit. Hence you will need to flip it by issuing gctx.ScaleCTM(1,-1), where the -1 specifies the flipping on the Y axis.
