based on #3031 Adds some examples showing of how to use the new pipelined rendering for custom shaders. - a minimal shader example which doesn't use render assets - the same but using glsl - an example showing how to render instanced data - a shader which uses the seconds since startup to animate some textures Instancing shader:  Animated shader:  (the gif makes it look a bit ugly) Co-authored-by: Carter Anderson <mcanders1@gmail.com>
