* Small cleanup in cellJpgDec and cellPngDec. * cellPamf added to the project and a few test lines added to cellPamfGetHeaderSize(2). * Improved speed of the Raw Image Preview on the the Memory Viewer. * Now you can click on the shown buffers / textures in the RSX Debugger in order to see them in full size. More settings added to the tabs. * Fixed cellFsStat in order to fix the crash aused by opening directiories. The solution is really *really* ugly. Once vfsDir is ready, I will replace it with something better.
