add info-box: sample-rate, bit-format.

-C background color (RGBA) 0xffffff80 (semi transp white)
-r rectified waveform shape
-F specify font for annotations
-t use timecode instead of sample-numbers for x-axis
-T timecode start-offset - override BWF header info
-M add meta-data to annotations.
-f FFT analyze, colour highlight peak freq.
In general: keep it professional (scientific) and simple.
I've been thinking of throwing some time at forking sndfile-spectrogram
which already has all required infrastructure (and more). I don't think
a dedicated libwaveform is needed. It's pretty straight forward, isn't
it? I was actually surprised that there's actually no sndfile-waveform
tool, yet! -- Yeah right. It's a gimmick :)

AFAIK you can use cairo-surface as OpenGL-textures.

Nope, none that you would not already know.
That reminds me: How are things going with SampleCat?
