SDL2: PSP: Fixed render-to-texture larger than screen

Browse Source 
I found if I try to make texture bigger than screen and use it as a frame buffer, it gets cuts of content. To ensure that render will be valid, I making sure scissors were initialised properly.

P.S. This works on hardware, however, emulator PPSSPP seems has a bug in this case, so I going to report that and making the simple demo.
