Routine Description:
This function enum all the forms from the spooler and return the FORM_INFO_1 arrary or using callback function to enum,
this function automatically filter out the form size which greater then the device can support, it also set the valid bits if the device can handle the form in the data base.
Arguments:
hPrinter - Handler to the printer
EnumFormProc - callback function, if NULL then no callback is performed
pEnumFormParam - Pointer to the ENUMFORMPARAM data structure, the count and pFI1Base will be set upon returned.
Return Value:
BOOLEAN - if FALSE then a memory allocation or EnumForms() call failed

15-Dec-1993 Wed 21:14:46 updated Make the form valid if it rotated and can fit into the device
12-Jul-1994 Tue 12:43:50 updated Move PaperTray checking into here, so it will not call out if the paper cannot hold by paper tray.
