  1. Pass dot / dash locations to clip shader in the VAO 

    Instead of loading dot and dash positions into the GPU cache, send them
as VAO arguments.  This avoids exceeding the maximum GPU cache block
size with very large border corners with hundreds or thousands of dot /
dashes.

This fixes the first panic from #2469, though performance is still
abysmal. Later changes can address performance issues.
