4294967295 is -1, so yes, the shader failed to compile. We do print a FIXME if
the shader fails to compile, but usually that happens long before
drawStridedFast is called, so it's not obvious the two are connected. We should
probably detect -1 shaders, print something, and perhaps just skip enabling the
relevant vertex/fragment program.
