    Treat VK_TIMEOUT as an error · 968df09e
    Tim Van Patten authored Nov 11, 2019
    The fence wait time was increased to 120 seconds, so we don't expect
    VK_TIMEOUT to be returned by a healty GPU. This change makes it so that
    when VK_TIMEOUT is returned, we will treat this as an error and
    propagate it to the GLES application as a GL_INVALID_OPERATION.
    
    It is expected that the GL application will re-initialize ANGLE which
    will also reinitialize the Vulkan device (and hopefully clean up the
    error). This is not our final design for ANGLE's VK_TIMEOUT handling,
    since we expect to expand our Vulkan device lost error handling when
    implementing the GLES 3.2 robustness requirements. This will likely
    improve ANGLE's VK_TIMEOUT handling as well.

    Test: Manually force VK_TIMEOUT (lower kMaxFenceWaitTimeNs)
