When processing a layer, we request the dependencies of all the SymbolBuckets even if we are not processing it completely. By doing that we are now requesting glyphs in parallel instead of sequentially as we were doing before. This patch is also simplifying the SymbolBucket creation code by getting rid of the ugly "needsResources" return value passed by reference as argument.
