Non square textures have wrong thumbnail

[Cubouse]

What are you trying to do, and what do you expect to happen?

Working with non square textures.

I noticed this issue while making a flipbook animation of a non-square texture, and looked at the thumbnail to tell what frame I was working on at a glance.

What happens instead?

The thumbnail in the Textures tab is still square. I found this to be more problematic with flipbook animations than for simple textures.

For simple textures:

• landscape-format makes the thumbnail align at the top. The full width is displayed, but leaves the bottom side of the thumbnail empty.
  

• portrait-format ones display the top of the texture, cropping the bottom
  

For flipbook animations:

• for a 32x16 flipbook animation, it shows two frames at once, the current frame over the next.

• for portrait-format flipbook animations, it's the same as a simple texture, the top part only is showed, filling the width of the thumbnail.
