Add an option to enable/disable texture smoothing while fullscreen turned on

[Zareef]

Hi, I just found out that the new versions produce more pixelated image than the old one (while fullscreen and "Enable saving GE screen to Textures" turned on).

old:

   

new:

   

And I think this line in REShader.java caused the problem:

re.useProgram(program); //remove this then the texture smoothing works.

now I can turn on texture smoothing by replacing REShader.class by the old one in jpcsp.jar, but still hope there can be an option to switch this. thanks.

It's look like weave (saw-tooth) interlacing on the new versions while fullscreen, maybe to increase performance.
The old one look like blend (slight blur) interlacing, maybe it is decreased performance. (I might be wrong)
