// This test comes from crbug.com/1355807 and crbug.com/1365578. The underlying issue was:
// * We would do a non-mipmapped draw of a proxy. This proxy would add a dependency from the ops
// task to the proxy's last render task, which was a copy task targetting the proxy.
// * We would do a mipmapped draw of the same proxy to the same ops task.
// GrRenderTask::addDependency would detect the pre-existing dependency and early out before
// adding the proxy to a resolve task.
// We also test the case where the first draw should add a MSAA resolve and the second draw should
// add a mipmap resolve.
