Bug 1179298. ClientTiledPaintedLayer should allow empty transactions to succeed if it doesn't need to draw anything. r=mattwoodrow

Browse Source 
ClientTiledPaintedLayer::RenderLayer was returning false immediately if there was no callback. It should check if it actually has to draw anything first, and then if it needs to paint it can return false if there is no callback.
