Because of the changes that Microsoft has implemented for Indic
rendering in OpenType, it is recommended to first test using MS fonts
from Vista/Windows 7. We can presume that the Vista/Win7 fonts have
been designed to render properly on the latest version Uniscribe.
Using these fonts, Behdad and others working on HarfBuzz can more
quickly achieve equivalent rendering results without having to worry
about bugs in the fonts themselves. Of course there *may* be bugs
still present in the Vista-fonts--Uniscribe rendering pipeline, either
on the font or Uniscribe side of things, but those can be documented
from visual inspection of rendered output.

PangoView. Behdad has already talked about modifying PangoView to
produce this kind of output. And PangoView is already cross-platform,
so we can use it to get both Windows and Mac rendering results, as
well as Linux of course.

Output should probably be individual PNG files -- one image file for
each test case. PNG files can be easily embedded in a web-based
resource, right along with the textual input and output data.
