+    this code is highly unlikely.  it is not haile selassie.
+
+    there is some hair here.  we can't just use the window's
+clip region as it is, because if we are painting the border,
+the border is not in the client area and so we will be excluded
+when we validate the GC, and if we are painting a parent-relative
+background, the area we want to paint is in some other window.
+since we trust the code calling us to tell us to paint only areas
+that are really ours, we will temporarily give the window a
+clipList the size of the whole screen and an origin at (0,0).
+this more or less assumes that ddX code will do translation
+based on the window's absolute position, and that ValidateGC will
+look at clipList, and that no other fields from the
+window will be used.  it's not possible to just draw
+in the root because it may be a different depth.
+
+to get the tile to align correctly we set the GC's tile origin to
+be the (x,y) of the window's upper left corner, after which we
+get the right bits when drawing into the root.
+
+because the clip_mask is being set to None, we may call DoChangeGC with
+fPointer set true, thus we no longer need to install the background or
+border tile in the resource table.

+the border is not in the client area and so we will be excluded
+when we validate the GC, and if we are painting a parent-relative
+background, the area we want to paint is in some other window.
+since we trust the code calling us to tell us to paint only areas
+that are really ours, we will temporarily give the window a
+clipList the size of the whole screen and an origin at (0,0).
+this more or less assumes that ddX code will do translation
+based on the window's absolute position, and that ValidateGC will
+look at clipList, and that no other fields from the
+window will be used.  it's not possible to just draw
+in the root because it may be a different depth.
+
+to get the tile to align correctly we set the GC's tile origin to
+be the (x,y) of the window's upper left corner, after which we
+get the right bits when drawing into the root.
+
+because the clip_mask is being set to None, we may call DoChangeGC with
+fPointer set true, thus we no longer need to install the background or

+    this code is highly unlikely.  it is not haile selassie.
+
+    there is some hair here.  we can't just use the window's
+clip region as it is, because if we are painting the border,
+the border is not in the client area and so we will be excluded
+when we validate the GC, and if we are painting a parent-relative
+background, the area we want to paint is in some other window.
+since we trust the code calling us to tell us to paint only areas
+that are really ours, we will temporarily give the window a
+clipList the size of the whole screen and an origin at (0,0).
+this more or less assumes that ddX code will do translation
+based on the window's absolute position, and that ValidateGC will
+look at clipList, and that no other fields from the
+window will be used.  it's not possible to just draw
+in the root because it may be a different depth.
+
+to get the tile to align correctly we set the GC's tile origin to
+be the (x,y) of the window's upper left corner, after which we
+get the right bits when drawing into the root.
+
+because the clip_mask is being set to None, we may call DoChangeGC with
+fPointer set true, thus we no longer need to install the background or
+border tile in the resource table.

+ *      A resource ID is a 32 bit quantity, the upper 2 bits of which are
+ *	off-limits for client-visible resources.  The next 8 bits are
+ *      used as client ID, and the low 22 bits come from the client.
+ *	A resource ID is "hashed" by extracting and xoring subfields
+ *      (varying with the size of the hash table).
+ *
+ *      It is sometimes necessary for the server to create an ID that looks
+ *      like it belongs to a client.  This ID, however,  must not be one
+ *      the client actually can create, or we have the potential for conflict.
+ *      The 31st bit of the ID is reserved for the server's use for this
+ *      purpose.  By setting CLIENT_ID(id) to the client, the SERVER_BIT to
+ *      1, and an otherwise arbitrary ID in the low 22 bits, we can create a
+ *      resource "owned" by the client.
