There is a tale told of Master Jim:
A student asked the master: "Does Imaging have Buddha Nature?"
And the master spoke at length of graphics states and clipping.
And the student said: "Now I understand Graphics."
And the master seized up a banana cream pie and smooshed it into the student's face.
The student ran away and attempted to write an app to interpret the I Ching.
And the app, it did not work.
And the student returned to the master.
And the student asked the master: "Does the PolyLine object have Buddha Nature?"
And the master spoke with wisdom of RoundRects and filled regions.
And the student said: "Now I understand Bresenham's Algorithm."
And the master whipped out a Nerf® gun and shot the unhappy student.
The student ran away and with the knowledge gained fixed the bugs in his app.
And the app, it was functional.
And the app, it was wondrous to behold.
And the app, it would not print its output to hardcopy worth a damn.
And the student returned to the master.
And the student asked the master: "Does Postscript® have Buddha Nature?"
And the master spoke truly of masks and halftones.
And the student said nothing, but ran away before the master could pelt him with Spam(tm).
The student approached his PC and his Sun Workstation.
And he turned off the Sun, and saw that it was good.
And with care he kicked his PC down 12 flights of stairs and declared it the Bonus Plan.
It so happened that the master was passing by the student's cubicle a few days later.
And he saw that the Sun was out.
And he saw that the PC was no longer.
And the master spoke: "Now you understand Graphics."
