G2D-test

Description

This sample game demo uses the G2D library. This game demo demonstrates the following:

How layers can comprise tiles of different materials.
How to design tiles so that the viewport can be rotated without creating artificial aliasing.
How to compose and separately scroll multiple layers.

For details about this library, refer to the 2D Graphics Library (G2D) in the Revolution Graphics Programmer's Guide.
