v0.1.0-dev.1

Breaking Changes

• Added WindowHandle, which allows interacting with the window after it has
  been built. This parameter is passed into nearly all Window trait functions
  now.
• WindowCreator now takes &self parameter for all methods. There was no
  reason for these methods to be static, and it prevented a window from being
  able to control how it was built based on its initial configuration.

Fixes

• Rendering a SpriteSource using a Point without specifying a Size now renders
  it at Scaled resolution. This restores the behavior before the parameters
  were switched to Displayable.
