					PREV      : Attach node as a previous sibling of the context node
					NEXT      : Attach node as a next sibling of the context node
					FIRSTCHILD: Attach node as the first child of the context node
					LASTCHILD : Attach node as a last child of the context node

				Locked:     Is node locked ?
				Mangled:    Is node mangled ?
				Marked:     Is node marked ?
				Selected:   Is node selected ?

> 	virtual BOOL NodeBitmap::AllowOp(ObjChangeParam* pParam,BOOL SetOpPermissionState = TRUE)

	Author:		Mark_Neves (Xara Group Ltd) <camelotdev@xara.com>
	Created:	3/02/95
	Inputs:		pParam				 = describes the way an op wants to change the node
				SetOpPermissionState = if TRUE the Op permission state of this node will be set according to
										the outcome of the call
	Outputs:	-
	Returns:	TRUE means the node and all its parents are happy with this op, FALSE means don't do it
	Purpose:	This is the way to ask a node if you can do an op to it.

				The ObjChangeParam class contains flags that describe how it will change the node

				For example, the op could change the node's appearence (e.g. attr application, editing a path), 
				replace the node with another node (e.g. because it uses hidden nodes to hide the original and put another
				node in its place, or "make shapes"), delete the node (e.g. the delete and cut ops), etc.

				This function gives the node a chance to say NO.  It also gives the parents a chance to say no too.
				E.g. a blend node will allow itself to be deleted, but it will NOT allow a child of itself to be deleted).

				This call should only be made on selected, or parents of selected, nodes.  It makes a decision as a 
				straight node if it is selected.  It makes a decision as a parent if it has selected children.

				E.g. NodeBlend::AllowOp(...op delete...)
					if the node is selected, then it will return TRUE (parents permitting), i.e. I can be deleted
					if the node is a parent of selected it will return FALSE (i.e. can't delete children of blends).

				So when the node is selected, you are asking the node if you can do the op to it.  When the node is
				a parent of a selected node, you are asking if you can do the op to one of its children.

				********

				If the 'SetOpPermissionState' param is TRUE, the following indented lines applies:
					The node's op permission state is set according to the result of this function.

					If TRUE  is returned, then the node's op permission state will be left unchanged.
						AND the parent's op permission state will be set to PERMISSION_ALLOWED

					if FALSE is returned, then the node's op permission state will be PERMISSION_DENIED,
						AND all it's parents (up to the layer) will be set to PERMISSION_DENIED

					Also, all parents of this node are called via their AllowOp() func with the same state 
					as this node.  This means that after this call, you can guarantee that all of its parents will
					have either a PERMISSION_DENIED or PERMISSION_ALLOWED state.

					Note: Even if this node tries to set all it's parents to have a PERMISSION_DENIED state, if any
					of its parents have previously been set to PERMISSION_ALLOWED they will remain in that state (see
					SetOpPermission()). Why? Well, it is possible for a parent node to have one child with a 
					PERMISSION_DENIED and another child with a PERMISSION_ALLOWED.  It this state the parent MUST be
					in state PERMISSION_ALLOWED, because at least one of its children will allow the op to happen to it.

					So, after this call:
						 	The op permission state for this node will be either left unchanged (and
							therefore remain PERMISSION_UNDEFINED), or PERMISSION_DENIED.

							The parent's op permission state will be either PERMISSION_ALLOWED, or PERMISSION_DENIED.

					This is so UndoableOperation::UpdateChangedNodes() will only call OnChildChange() on parent nodes,
					because it only calls that func for nodes that have an op permission state of PERMISSION_ALLOWED.

	Returns:	TRUE  = This node supports the given format
				FALSE = This node does not support the format (or the format is unknown)

	Purpose:	Determine if a node supports a given internal data type. This is used
				by the clipboard when exporting to other applications in order to
				determine if certain data types can be supplied.

				e.g. The basic formats include:
					Vector		- this is ALWAYS assumed to be available (Vector format
								  includes every Node, e.g. export in Camelot .art format)

					Text		- As well as paths, some objects can provide text chars

					Bitmap		- Bitmap fills can render a filled object or supply the
								  bitmap used for filling with.

				See InternalClipboardFormat (kernel\cliptype.h) for more details

	Notes:		TextChars can be exported as either "vector" or "text" data

				This function supports nodes that use more than one bitmap - you call this
				function repeatedly and keep incrementing the Count parameter that you pass
				in each time by 1.  You should stop calling it when it returns NULL, as this
				indicates that no more bitmaps are used by this node.
				Count should start off as 0 for the first call.  Note that this function
				can (and often will) return NULL for the first call, as many nodes don't
				use bitmaps, obviously.
