Does anyone know if stylesheets are parsed everytime the associated objects are painted or whether there is some kind of compilation behind the scenes that takes place to improve performance (Eg. converting to byte code) ?

Does anyone know if stylesheets are parsed everytime the associated objects are painted or whether there is some kind of compilation behind the scenes that takes place to improve performance (Eg. converting to byte code) ?
The "Q"
Re: Stylesheets Performance
