* Move GPU LLE emulation from HLE to Graphics * Graphics: Move Gal/Texture to Texture * Remove Engines/ directory and namespace * Use tables for image formats * Abstract OpCode decoding * Simplify image table * Do not leak Read* symbols in TextureReader * Fixups * Rename IGalFrameBuffer -> IGalRenderTarget * Remove MaxBpp hardcoded value * Change yet again texture data and add G8R8 flipping * Rename GalFrameBufferFormat to GalSurfaceFormat * Unident EnsureSetup in ImageHandler * Add IsCompressed * Address some feedback
