[Sugar-devel] More information on font scaling problem

[James Simmons]

Tomeu,

The thing is, in the code below I *am* using style.zoom.  It seems to 
have no effect at all.

My test environment on Fedora 10 is .82.  My XO, running the latest (I 
believe) release candidate of Sugar is .82.  Most of the XO's that might 
use Read Etexts will be running .82 or worse and will not be eager to 
upgrade.  For that reason I'm trying to make my Activity work around the 
limitations of older versions of Sugar.  As an example, .82 still has 
the bug that custom metadata is not saved across reboots.  I was using a 
custom metadata field to store the page number that the user stopped 
reading on.  In my latest this page number is saved at the end of the 
Title of the Journal entry, like this:

Aleksey and I also put in code that suppresses the Speech tab when 
neither speech-dispatcher nor the gstreamer plugin for espeak is installed.
