Comment:

 [attachment:9257.diff] updates the previous patch to apply cleanly after
 [42343]. It also has the following adjustments:

 - Coding standards fixes.
 - Moves the latitude & longitude keys into an array stored in the
 `location` key.
 - Add the `wp_read_image_geo_data` filter. Returning a falsey value to
 this filter will disable all processing of location data.
 - Only adds the `location` key to the meta array if the parsing location
 data is not disabled with the `wp_read_image_geo_data` filter.
 - Limits the GPS decimal precision to 7 (practical limit of commercial
 surveying).
 - Updated other image meta tests to check for empty location info.

 To address @melchoyce's concerns, these changes will only parse the
 location data into image meta so that plugins and themes can utilize it.
 We could expose the data in the admin on each image, but I think that is
 best for a separate ticket.
