Thanks Jon, I didn't know I could do that!


So... I did a bit of playing and things work if you use
vContext.SetRGBStrokeColor (1.0f, 0.0f, 0.0f, 1.0f); but don't work if you use
vContext.SetStrokeColor (new float [] { 1.0f, 0.0f, 0.0f, 1.0f });

Turns out that if you want to use vContext.SetStrokeColor() or .SetFillColor(),
you need to first make sure that the CGContext's ColorSpace is in the
ColorSpace you want to use. It's probably defaulting to CMYK or something (it's
obviously not RGB).

you can do this by doing:

vContext.SetStrokeColorSpace (CGColorSpace.CreateDeviceRGB ());

before you call SetStrokeColor().
