Added Texture.MipCount
Texture gets desc from GetTextureDesc instead of GetOnDiskTextureDesc
Allow texture store and lookup (really all resources should be doing this)
Made some stuff in rect readonly
Render.SetRenderTarget takes an optional miplevel
Render.SetCombo takes an int instead of a byte (qol)
Attempt to bind everything we need to make CGaussianBloomBlurRenderer in c#
