* 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.
