968 This is the routine which an external caller uses to direct the browser
969 where to obtain it's information.
972 @param This The Form Browser protocol instanse.
973 @param Handles A pointer to an array of Handles. If HandleCount > 1 we
974 display a list of the formsets for the handles specified.
975 @param HandleCount The number of Handles specified in Handle.
976 @param FormSetGuid This field points to the EFI_GUID which must match the Guid
977 field in the EFI_IFR_FORM_SET op-code for the specified
978 forms-based package. If FormSetGuid is NULL, then this
979 function will display the first found forms package.
980 @param FormId This field specifies which EFI_IFR_FORM to render as the first
981 displayable page. If this field has a value of 0x0000, then
982 the forms browser will render the specified forms in their encoded order.
983 ScreenDimenions - This allows the browser to be called so that it occupies a
984 portion of the physical screen instead of dynamically determining the screen dimensions.
