- 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.

- this code is highly unlikely. it is not haile selassie.

-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.
