texture: Update the request mode depending on the size

Browse Source 
If a Texture has been set to:

  • keep its size synchronized with the image data
  • maintain the aspect ratio of the image data

then it should also change its request mode depending on the orientation
of the image data, so that layout managers have a fighting chance of
sizing it correctly.
