Changes

Eliminate:

public abstract void xform(float x, float y, Point into);
public abstract void xform_horiz(float x, float y, Point into);
public abstract void xform_vert(float x, float y, Point into);

public abstract void getExtRect(Rectangle into);

public abstract void getClipRect(Rectangle into);

public abstract float getAspectRatio();

public abstract void invert(float xs, float ys, float[] xyout);

Also, all render() methods should only get one RenderInfo object, as it will mostly be about colors.

The render() method's new prototype would be

public void render(Graphics g, VobCoorder coords,

int cs1, int cs2, Vob.RenderInfo ri);
