// TextureProxies & GrUniqueKeys
//
// The two GrResourceCache methods assignUniqueKeyToProxy and findProxyByUniqueKey drive
// the behavior of uniqueKeys on proxies.
//
// assignUniqueKeyToProxy does the following:
// if the proxy is wrapped, it sets the texture & proxy keys & adds the proxy to the hash
// if the proxy is deferred, it just set the unique key on the proxy & adds it to the hash
//
// Note that when a deferred proxy with a unique key is instantiated, its unique key will be
// pushed to the backing resource.
//
// Futher note, a proxy can only receive a unique key once. It can be removed if Ganesh
// determines that the key will never be used again but, in that case, the proxy should
// never receive another key.
//
// findProxyByUniqueKey does the following:
// first looks in the UniqueKeyProxy hash table to see if there is already a proxy w/ the key
// failing that it looks in the ResourceCache to see there is a texture with that key
// if so, it will wrap the texture in a proxy, add the proxy to the hash and return it
// failing that it will return null
