Extra

I have add Gaussian Blur, Glow, and RGB Adjustment to the program.

I want to quote credit to Mr. Jerry Huxtable, he's also a programmer, which also code a program which is similar to my assignment, and he wrote a article discussing various type of blurring and how to perform the calculation.

I also put in a Moveable JScrollPane which pan around the image. I re-use the codes from my previous group assignment, since the scrollpane from the particular assignment is very close to what I want, I did some re-calibration, and fit it into my program.
