Why would the alpha channel work differently with the same image from the
same code with the same hardware
depending on the driver? (I've already tried setting it to a 50% alpha just
in case it was something like a bug
in drawterm not honouring the alpha channel and I was doing something
stupid. The 50% alpha worked fine
in drawterm but didn't change anything locally..)
