Gives control over ordering of asset import based on types. Positive values delay the processing of source asset files while Negative values place them earlier in the import process.
This allows for basic dependency of asset imports, for example, one could have a custom asset type that must be run after all image files have been imported or after an other type of custom importer has executed. Usefull values range between -3000 and greater than zero. Negative values allow the execution to occur before native importers are run (each native type has it's own queue order).
