Drawing ground with texture.

The result looks more realistic of the ground. The texture is 16 bits color 565(RGB) bitmap.

If anyone want to try the texture with 16 bits 565 bitmap may use the OPENGL function follow.

Ex) glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB5, width, height, 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, data);
