Have Programmable Filter access global data, and document it.
Please add the ability to have the Programmable Filter access global data, and please document it (including an example) in the ParaView guide. This would be used to create a point array with this global data, so it could be used by other filters such as the calculator. As an example this generic functionality would be used to multiply can.exo's Accl magnitude by ke (a global variable).
