Changes:

• Expanded map to the right to show Trajan reaching Persian Gulf. I drew in that part of the map by hand, so may not be quite to scale but should be fairly accurate.
• Adjusted territory borders for the 117 AD frame based on the August 2013 version of File:Roman_Empire_Trajan_117AD.png.
• Changed frame rate so that each second corresponds to roughly 50 years, though the speeds have been partially "equalized" for readability. For example, instead of having a delay of 1/50th of a second between the 117 AD frame and 118 AD frame, a delay of 0.4 seconds was used, which I determined using ([proportionate delay] * 2 + [average delay])/3 rounded to 1/10th of a second. This formula was applied to all frames, which also helps to speed up frames with high delay.
