[scale-effect][patch] Add scale: 'textbox' option

[lrbabe]

There are several reasons to change two lines of code in the scale effect. You should read the (very simple) attached patch first and then read the followings.

• it saves two precious tests :)
  
• it saves some precious bites of code :)
  
• it shouldn't break anything
  
• when using scale effect on an element containing sub element with dimensions only in % or em, you will want only the container dimensions and the text font-size to scale. Moreover, there are some bugs in the scale effect on element with % dimensions.
  

I have attached some kind of example to show that (unzip attached presentations, open them, use left arrow to go to next slide, right to go to previous): In the presentation without textbox, background images sometime disappear (go to previous slide), foreground images appear when they shouldn't (third slide)

I have named this option 'textbox' but I'm not proud of this name.

Even with the textbox option, there is still bugs in IE and firefox (not tested in safari). It seems that browsers really don't like those kinds of effects.

Replying to lrbabe:

Is there any chance you can mock these presentations up with some fiddles, perhaps revisit this patch and submit a pull?

We'll need simpler test cases to look at.
