in awt applets, all parameter names are converted to all lower case.
in stand alone JavaFX they are case sensitifve.
They should also be case sensitive in JavaFX applications embedded in a web page.
decided to stror parameters in mixed case and only translate names to lower case when extracting and toolkit is awttoolkit
Fix is to keep raw map of parameters as addition to "normalized" map and provide API to access it for those who need it,
