Write one or more functions to create automatic mipmaps whenever a Texture's data is manually altered or is loaded from a PNG. This is a simple downscale by a factor of 2 in each dimension (or one dimension, if one of the dimensions is already 1).

Store these mipmaps in the Texture object and demonstrate it working with debug code. You do not need to enable the use of the generated mipmaps for rendering, that may be a future GCI task.

While working on this task you should join and remain in #PySoy on Freenode to get help, feedback, and guidance from mentors and other developers. Code updates which may affect your work are also announced here as they happen. This is especially important for this task as other GCI tasks may be worked on to modify the same class.

When you've done, commit your work and post the resulting changeset url to this task.
