Some of the classes for extending GameChips for PixelVision8 (and making their use more attribute-y and generic-y/reflect-y)

EngineExtensionMethods.cs

using PixelVisionSDK.Engine;
using PixelVisionSDK.Engine.Chips.Game;
using System;
using System.Linq;

namespace PixelVisionSDK.Extensions
{
    public static class EngineExtensionMethods
    {
        public static void LoadExtendedGameChip<T>(this IEngine engine, T gameChip) where T:GameChip
        {
            LoadExtendedGameChip(engine, gameChip, typeof(T));
        }
        public static void LoadExtendedGameChip(this IEngine engine, GameChip gameChip, Type type)
        {
            type
                .GetCustomAttributes(typeof(ChipDependencyAttribute), true)
                .Select(x => (ChipDependencyAttribute)x).ToList()
                .ForEach(x => engine.chipManager.GetChip(x.Dependency.FullName, x.ActivateOnCreate));

            engine.LoadGame(gameChip);
        }
    }
}

ExtendedDrawSpriteDemo.cs

using PixelVisionSDK.Engine.Chips.Graphics.Sprites;
using PixelVisionSDK.Engine.Chips.Graphics.Colors;
using PixelVisionSDK.Engine.Chips.Graphics.Display;
using PixelVisionSDK.Engine.Chips.IO.Controller;
using PixelVisionSDK.Extensions;

namespace ExtendedDemos

    [LogicalSize(256,240)]
    public class ExtendedDrawSpriteDemo: DrawSpriteDemo
    {
    }
}

GameChipExtensionMethods.cs

using PixelVisionSDK.Engine.Chips.Game;
using System;
