Rails Riders,

For those who like “prawning PDF docs to their RoR apps” :  
Text::Box has been patched to default the text-box height in stretchy  
boxes  
to the distance to the bottom of the page if no height is supplied (or  
if  
overflow is :expand).

> zero).

Peace,

Subject: [dev] RFC: Text::Box in stretchy bounding box uses margin\_box  
for  
default height

In an effort to fix tables inside spans [#142], I have pushed the  
following commit to master:

Previously, Text::Box would refuse to render inside a stretchy  
bounding box because the height to the “bottom” of the box was zero.  
I’ve patched this to default the text-box height in stretchy boxes to  
the distance to the bottom of the page if no height is supplied (or if  
overflow is :expand). This has not yet fixed the table problem, but  
it’s getting better.

I’m generally pretty cavalier about pushing stuff that passes all of  
the specs, but I wanted to throw this out there for review in case  
there might be a corner case I’m missing.
