# Constants to use
#
# Regions of a window
ShapeBounding = 0       # the 'edge' of a shaped window
ShapeClip = 1           # the clipping region
# Shape Operations
ShapeSet = 0            # Set the region unmodified (dest=src)
ShapeUnion = 1          # Add the new region to the old (dest=src|dest)
ShapeIntersect = 2      # Use the intersection (dest=src&dest)
ShapeSubtract = 3       # remove region (dest = dest - intersect)
ShapeInvert = 4         # opposite of subtract (dest = src - intersect)
# Events
ShapeNotifyMask = (1<<0)        #a keypress mask?
ShapeNotify = 0                 #still unsure of these values

# How to Use
# The basic functions that change the shapes of things are:
#   shape_rectangles (uses a set of rectangles as the source)
#       operation, region, ordering, rects
#   shape_mask (uses a bitmap as the source)
#       operation, region, x_offset, y_offset, bitmap
#   shape_combine (uses a window as the source)
#       operation, src_region, dest_region, x_offset, y_offset, src_window
#   shape_offset (moves the region)
#       region, x_offset, y_offset
# The functions to find stuff out (these three return mappings of field/values):
#   shape_query_version (shape extension version)
#       major_version, minor_version
#   shape_query_extents (rectangle boundaries of a window's regions)
#       clip_shaped, clip_x, clip_y, clip_width, clip_height,
#       bounding_shaped, bounding_x, bounding_y, bounding_width, bounding_height
#   shape_input_selected (if the window products shapenotify events)
#       enabled
#   shape_get_rectangles (the rectangles set by shape_rectangles)
#       ordering, rects
# And to turn on shape notify events:
#   shape_select_input
#       enable
