1. trying to learn about openGL objects, I noticed that the correlation of _blend_mode_ and _blend_ seems to be different to what is in the manual. This is confusing.

2. Whilst trying to save my work, I discovered that what gets saved is not what I see in the jit.window.

I'm sure there's a reasonable explanation for this, but I'm not seeing it! Any tips would be very welcome! Thanks!

1) Could you please provide examples of the wrong blend_mode/blend correlation?

2) The export looking different from the rendering window might depend on the alpha values. 

Try to discard the alpha plane and substitute it with a solid 1:

thanks for the illustration, Matteo. Here's the same patch with some remarks about the blend_mode/blend correlation. There is only one which is different to what's in the manual, but often the communication between blend and blend_mode seems to break down, which is what I originally noticed without understanding it.
