Radial Blue and something else. Options

[Jens of Zanicuud]

Hello everyone,
this time it's me who needs help 0.o

I'm trying to implement RMVX scripts in RMXP (if you browse the forum a little, you'll notice a nice submission called RMVXP 0.8.4... or whatever).
The problem is... I'm not able to script these things by myself:

class Bitmap
>Gaussian Blur (the one I made is a sort of fake blur);
>Radial Blur (like in RMVX - the effect applied to the battle background);

class Window
>Window viewport change (that is, changing the window's viewport after the window's declaration)
- this one is the most urgent

I hope someone will be able to help me,

Jens
