Subject: [PATCH] * Implements IGraphics interface for MRM Scripting. * This
 allows you to utilize System.Drawing tools on textures within the region. *
 Example: use System.Drawing.Bitmap to make your texture, then use
 Host.Graphics.SaveBitmap to make an asset from it in JPEG2K. You can edit
 (but not overwrite) existing textures using Host.Graphics.LoadBitmap.
