found nvidia eat-cpu-bug. glXWaitGL() spins using all cpu it can find,
though nvidia fixed the spinning on glXSwapBuffers() long ago, they didn't fix this one. SVN revision: 66710

* Add recursive name find function - evas_object_name_child_find()

* Improve CPU use on nvidia drivers when vsyncing. It was
|
||||
actually glXWaitGL() spinning, not glXSwapBuffers(), so this
|
||||
points to a bug in the nvidia drivers where the sleep logic
|
||||
in glXSwapBuffers() hasn't been transferred to glXWaitGL().
|
||||
Avoid use of glXWaitGL() to avoid the nvidia bug.
