commit ba4ffba8c164400acf662eea7b7a715093812f12
Author: Jean-Philippe Andre <jp.an...@samsung.com>

Evas: Add a test case for image buffer_map.
This:
1. opens a file
2. maps its data and vaguely verifies it
3. writes data to it
4. writes data to it with a GRY8 map
5. verifies that the final image has all the proper pixels
