Changed test settings
Added support for a render resolution separate from the screen resolution (allows for scaling).
Modified the nsconfig parsers for screen width/height to set the rendering resolution as well as the screen resolution.
Added support for saving scaled images to file.
Added support to ScreenDrawer for upscaling and pixel interpolation (they're moderately slow but work well.)
Added keyboard shortcuts for testing/tuning performance in real-time.
Added support for a "dirty" flag used by the renderer to determine if a camera was modified mid-render.
Added the ability to set a Color via an integer.
Code cleanup
Added support for dirty camera detection and variable render resolution.
