Added Surface type - as a simple value type to hold a 2d collection of pixels. (#548)

Added PngSerializeUtil allows currently for just writing Surface of RGBA format.
Removes dependency on stbi_image except for in PngSerializeUtil.
Removed use of gWindowWidth/Height globals - pass the height into initialize or Renderer.
