bad news

just check it and seems that Rasterizer works only with primitive shaoes (drawRect, drawCircle) or text (drawText) but not with Bitmap

so you can forget about Rasterizer, sorry...

Just go opengl, take a look at the Replica Island code. Good stuff. Look at the "Grid" class, which is an extended version of the Grid class from the SpriteMethodTest.

It's an VertexGrid with Triangles inside it, packed 2 connected to generate a quad, texturizing them with uv coords from an given texture and draw them in one call (or using screensize/tileheight strips for large maps with scrolling).

That looks really interesting. I'm downloading the Replica Island code and I will try it now. Thank you!
