<p>What we wanted to do was:<br />
Unbox the shared_pointer<GBMSurface> to give us a GBMSurface* object<br />
Call the gbm_surface*() on that operator<br />
Then cast that to a void* for eglCreatePlatformWindowSurfaceEXT</p>
<p>What we did:<br />
Cast the std::shared_ptr<GBMSurface> to a gbm_surface* then cast that<br />
to void*.<br />
This is just a garbage value and it crashes in Mesa when we do our first<br />
paint.</p>
<p>I've replaced that with an explicit method then we can use shared_ptr's<br />
-> operator rather than get() which does the right thing in a readable<br />
way.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>It crashed after rebasing to master (for Aleix too)<br />
