Too many points in wavelet spectrogram plot

[jchutrue]

If there are too many points in the wavelet spectrogram plot, some parts of the image will not render properly. I need to figure out a way to downsample correctly without messing up the temporal resolution.

Well, we may just need to use the right tool for the job. Matplotlib is not the right tool, but datashader might be: https://github.com/pyviz/datashader

I was thinking about PyOpenGL but this looks pretty cool and may be faster to get working

i'ts a three-liner to plot your spectrogram with datashader, so it looks like a winner to me
