Did you particularly need this change? The reason I didn't make this const is
that it returns a non-const PpapiHost* which is really internal state of the
RendererPpapiHost object. So semantically, the constness of the getter should
match the constness of the return value in this case (even though it compiles
either way).

No, we can remove the const-ness up to RendererPpapiHost::GetPlatformGraphics2D.
 Done.

 
   // Returns true if the given PP_Instance is valid and belongs to the
   // plugin associated with this host.
   virtual bool IsValidInstance(PP_Instance instance) const = 0;
 
   // Returns the RenderView for the given plugin instance, or NULL if the
   // instance is invalid.
   virtual RenderView* GetRenderViewForInstance(PP_Instance instance) const = 0;
 
+  // Returns the PlatformGraphics2D for the given plugin resource, or NULL if
+  // the resource is invalid.
+  virtual webkit::ppapi::PluginDelegate::PlatformGraphics2D*
+      GetPlatformGraphics2D(PP_Resource resource) const = 0;
+
   // Returns true if the given instance is considered to be currently
   // processing a user gesture or the plugin module has the "override user
   // gesture" flag set (in which case it can always do things normally
   // restricted by user gestures). Returns false if the instance is invalid or
   // if there is no current user gesture.
   virtual bool HasUserGesture(PP_Instance instance) const = 0;
