if your plane is 100x20, and you make a 100x20 image with your text, then change the size to 128x32, it will be displayed in ratio of your plane, 1/1 100x20 exactly as you wish so no matter the eventual distort the original image gets, it will be corrected automatically. Even if you make your image 1024x1024, its will be spreaded and displayed entirely over your plane at 100x20 And yes, you could change the uv's but why bother as its so easy to do by just saving the image in ratio.
you can use different values for the image source dimension, as long as both width/height are power of 2. 2,4,8,16,32,64 etc... It doesn't have to be a square. if you add extra maps, for instance if you make a BitmapMaterial and add a normalmap, the normalmap has to be of the same size as the diffuse map. If you don't respect these rules, the engine will remember it to you anyway.
