EMF manual 2.2.9, Microsoft name: Header object, HeaderExtension1 object, HeaderExtension2 object
Microsoft names instead: Header, HeaderExtension1, and HeaderExtension2 objects. These are used nowhere else, so they are combined here, along with the first two fields which were not listed in the Header.
Note also that three fields in this file (nBytes, nRecords, nHandles) must be (re)set after the entire EMF is constructed, since typically they are not known until then. bOpenGL may or may not be knowable when this header is written.
Note also that rclBounds and rclFrame are supposed to be the region bounding the drawn content within the EMF. This is generally smaller than the size from szlDevice. However, since libUEMF does not actually draw anything it has no way of knowing what these values are. Instead when it creates a header it sets these to match the szl* fields.
