Is this stylistically correct for nestled namespaces?

[nfullagar, 2011/08/18 00:23:57]

looks strange but I think that's what we do.

+class GLES2CmdHelper;
+class GLES2Implementation;
+}  // namespace gles2
+}  // namespace gpu
+
+namespace ppapi_proxy {
+
+// Implements the plugin (i.e., .nexe) side of the PPB_Graphics3D interface.
+class PluginGraphics3D : public PluginResource {
+ public:
+  PluginGraphics3D();
+  ~PluginGraphics3D();

Classes having virtual functions always have virtual destructors.  BTW, is the
Dtor in PluginResource virtual?

good catch - kargo-kulted over from plugin_context_3d.h (and plugin_surface_3d.h
and those are going away)

+
+  static const PPB_Graphics3D_Dev* GetInterface();
+  static const PPB_OpenGLES2_Dev* GetOpenGLESInterface();
+
+  virtual bool InitFromBrowserResource(PP_Resource graphics3d_id);
+
+  gpu::gles2::GLES2Implementation* impl() {
+    return gles2_implementation_.get();

+
+  int32_t SwapBuffers(PP_Resource graphics3d_id,
+                   struct PP_CompletionCallback callback);

alignment.

Done.
