Done.

if you want to keep this function around put it behind a debugging define and
default the define to 0 at the top of the file.

[tomhudson, 2014/08/04 21:03:57]

Done.

Reused SK_DEBUG_FONTS instead of creating a custom define?

+    for (int i = 0; i < fontFamilies.count(); ++i) {
+        SkDebugf("Family %d:\n", i);

I think there is some kind of GetResourceDir function so we don't hardcode
/data/local/tmp.

[tomhudson, 2014/08/04 21:03:57]

Done, after much argumentation.

It is now necessary to pass  --resourcePath /data/local/tmp/resources/  to the
test runner.
