//
// "Helv"
// This is used by Excel. It is mapped directly onto "MS Sans Serif".

// "MS Dialog"

// We actually map it to a "MS Sans Serif" font that is one pel narrower
// than the metrics specify (because all matching is done on non-bold
// fonts) - hence the 1 value in the charWidthAdjustment field.

// "MS Dialog Light"
// Added as part of the Win95 performance enhancements...Presumably for
// MS-Word...

//
// If this fails somewhere, we accumulate screen data in the same place
// to spoil the order(s).
//
//
// NOTE:
// There are some VERY important things about the way this function
// works that you should be aware of:
//
// (1) Every time an order is allocated, it is added to the end of
// the order heap linked list
// (2) Appending an order commits it, that updates some total byte info.
// If the order is a spoiler, the append code will walk backwards from
// the order being appended and will wipe out orders whose bounds are
// completely contained within the rect of the current one.
//
// THEREFORE, it is important to append orders in the order they are
// allocated it. When we come into this function, one order is already
// allocated. Its rcsDst bound rect is uninitialized. When a second
// intersection with the visrgn occurs, we must allocate a new order,
// but append the previously allocated block with the previous rect
// info.
//
// Otherwise you will encounter the bug that took me a while to figure
// out:
// * Laura allocates an order in say PatBlt with a spoiler ROP
// * Laura calls OEClipAndAddOrder and of course the rcsDst field
// hasn't been initialized yet.
// * The order intersects two pieces of the visrgn. On the first
// intersection, we save that info away.
// * On the second, we allocate a new order block, fill in the NEW
// order's info by copying from the old, setting up the rect
// with the first intersection, and call OA_DDAddOrder.
// * This, as a spoiler, causes the OA_ code to walk backwards in
// the linked list looking for orders whose bounds are
// completely enclosed by this one.
// * It comes to the original order allocated, whose bounds are
// currently NOT initialized
// * It may find that these uninitialized values describe a rect
// contained within the new order's bounds
// * It frees this order but the order was not yet committed
// * The heap sizes and heap info no longer match, causing an
// error about the "List head wrong", the list to get reinited,
// and orders to be lost.
