BUG: Components' weight and height fields are switched

Before: http://cl.ly/LTWL
After: http://cl.ly/LS2Q

“height” alters width and “width” alters height.
Also “Width” is indicated with “v”.

This is not a bug. The “h” field means Horizontal scale, and the “v” means vertical scale. I added a tooltip to make that clearer.
