+## Features
+
+* Layers: Draw to multiple independent layers
+* RGB drawing: Draw in 32bit rgba colorspace
+* Pal drawing: Draw in palletized 8bit colorspace and change the palette on the fly, without needing to redraw
+* Image loading: Load and save from and to multiple file formats
+* OpenGL 2.1: It's old. It's antiquated. I mean, who needs shaders anyway?
