-A video game looks abstractly like
+<pre>/* Get the 2D device function pointers. */
-<pre>
+NPDevice* device2d = extensions->acquireDevice(npp, NPPepper2DDevice);
-  ...
-  while (true) {
-    HandleEvents()
-    Simulate(gettimeofday())
-    Draw()

-We propose that we continue to set graphics attributes through the existing NPN_GetValue/NPN_SetValue interfaces with some new variables TBD.
+/* Create a context. there are currently no options
+   in the 2D device to configure */
+NPDeviceContext2DConfig config;
+NPDeviceContext2D context;
+device2d->initializeContext(npp, &config, &context);
-There are four APIs that would be involved in supporting this from the browser.
+/* Draw into the bits in context->region however you want. */
