ID 465739 - Import: The png used for future publishes (fullres media object) is rendered at low resolution, with a width of 1000px

Problem summary
The fullres media object (image used for publishes) is no longer actually full resolution, but is instead the same size as the thumbnail. This causes panels to appear slightly blurry when sent to Editorial.

Customer reported version
Flix 6.3.6

Steps to reproduce

This bug reproduces every time still panels are imported into Flix, at import time. Steps to view the fullres that is generated in the background are below.

Note: following these steps requires usage of the Flix Dev Tools and searching through the MySQL database.

1) In Flix, go to View > Dev Tools and open the Network tab, then import a panel into an empty Revision and save. Bug reproduces across aspect ratios so it's irrelevant what you use.

2) Under the Name column in the Dev Tools, click on the panels request, and make note of the asset_id for the panel just imported, as well as the show_id.

3) In MySQL, search for the name of the fullres stored in the assets directory for the panel you imported.

SELECT id,filename FROM <db_name>.media_object where asset_id=? and ref='fullres';

4) Grab the file you need from the show folder in the assets directory based on the information found from the SQL search. File will be named id_filename.

5) Open the file in Photoshop, and check the image size. It will be the same dimensions as the thumbnail.

Expected behaviour
The fullres should fit the original artwork to the Show's aspect ratio, without decreasing its resolution. Some examples:

~ If panel is using the PS template, the fullres should be 2000 px long, height dependant on aspect ratio (letterboxing removed).

~ If panel is from SBP, the fullres​ should be the same exact size as the original artwork (usually 1920 px long, and height dependant on aspect ratio).

~ If the panel was imported with an aspect ratio different from that of the Show's: 

Actual behaviour
Original artwork's resolution is decreased. The fullres is 1000 px long, with a height dependant on the aspect ratio.
