Here's another question that's probably been asked a hundred times:
Is there a way to get a Graphics context to draw on when using hardware rendering mode? I can't use getGraphics() since, as the Javadoc states, "when using OpenGL support, this value is rather meaningless".
I suppose I could draw my layer onto an Image, and use that to create a Texture to use in the blit() method. I'd have to rethink how I handle images that change dynamically (since I wouldn't want to create a new texture every frame). Also, is a texture's alpha information taken into account by blit()? If not, is there another way to draw simi-transparent 2D stuff on top of the rendered scene?
--EDIT-- I see that one of the blit() methods has the ability to set an additional color. I'll play around with this to see if I can get the results I'm looking for.
