I stopped using my code and just made a copy of svgspritetest.activity. I am
using it instead and just trying different SVG files that I am making.
At this point my problem seems to be one of color. I have since learned that
the colors of my original images were not distinguishable. I seem to
remember somewhere that you all are using a 16 bit palette. It could be that
I am making images that are 32 bit and when it maps them to 16 bit they
change. I say this because I made some new images with more colors in them
and they now display with distorted color in svgspritetest.activity.
The colors are just wrong, i.e., Red shows up as blue for example. This leads
me to believe that all my images have been displayed but that I can't see
some of them because they have been mapped to the same color as the
I am not sure what to do about this.

My initial images did not show anything.

My initial images were 48x48 pixels. The activity.svg image included with
svgspritetest.activity is 45x45.
