Moving tiles in TurtleArt let a trace on the screen

[sayamindu]

From ​http://dev.laptop.org/ticket/9678:

In TurtleArt, moving tiles with number (forward, left, ...) let a trace on the screen. The trace disappear when the screen is refreshed. It seems that the font size used for number is too large.

It seems that changing the default font-size helps.

As I pointed out in ​http://dev.laptop.org/ticket/9678, this seems to be an artifact of a general font-scaling problem on the OLPC XO 1.5. It doesn't make sense to try to address it in individual activities.

Turns out the "system-wide" font scaling problem was not the problem after all. The way I was detecting XO hardware no longer worked on the XO 1.5 machine so I was applying the non-XO font scaling to XO. I now (as of v79) use /etc/olpc-release to detect XO hardware and the problem should be fixed.
