When stretching=uniform, fill screen if just not filling.

It's very common for videos and/or preview images to just not exactly fit the display. This because of:

• mod_16 limitations around encoding (some video dimensions are mod_16, others are mod_8, others are not)
• adaptive streaming and mod_xx limitations (during a streaming session, the small bars will show or not).
• mod_xx in combination with preview images (you then have to basically choose: make the image fit the screen or the video)

This leads to annoying small black bars above/below or left/right of the video.

We should fix this issue in the Stretcher by sticking the element to the container dimensions if its dimensions are just a little bit off. For example:

1. The stretcher calculates the object dimensions for uniform stretching.
2. If the dimension that's smaller than the container is <5% smaller, set it to the container dimension.

Updated the ticket to not have this as additional mode, but just small enhancement.

We should experiment with the threshold - what percent change will the aspect ratio change be noticeable?
