OpenGL Render Thread Resizing when Component Resized

[timart]

Great, it seems this is the case since in juce_OpenGLContext.cpp the renderFrame() method begins by getting a Message Manager lock:

bool renderFrame()
{
    MessageManager::Lock::ScopedTryLockType mmLock (messageManagerLock, false);
    ...
}

@PluginPenguin Thank you for the help!
