Can render both the julia and mandelbrot set using a fragment shader. This demo was used to demonstrates GPU shader performance by using up roughly 515 instructions to render each fragment while generating the julia set.
It uses no textures, has no overdraw and has a minimal bandwidth requirement.
Use the commandline arguments to select the scene and quality.
Command line arguments':

| -a, --AnimMode <arg> | Chose the julia animation mode. | Demo |
| -d, --Demo | Lock into demo mode (nothing can be overridden). | Demo |
| -f, --ForceUnroll | Force unroll the shader loops. | Demo |
| -i, --Iterations <arg> | The number of iterations to perform (>=1). | Demo |
| -q, --Quality <arg> | Select the rendering quality (low,medium,high). | Demo |
