#
# A window device context allows drawing into an FXDrawable, such as an
# on-screen window (i.e. FXWindow and its derivatives) or an off-screen image (FXImage
# and its derivatives).
# Because certain hardware resources are locked down, only one FXDCWindow may be
# locked on a drawable at any one time.
#
class FXDCWindow < FXDC
#
# Construct a device context for drawing into a window (specified by _drawable_).
# If _event_ is +nil_, the device context is constructed for normal drawing, and the
# clip rectangle is set to the whole rectange.
# If _event_ is a reference to an FXEvent, the device context is constructed for
# painting in response to an expose; this sets the clip rectangle to the exposed rectangle.
# If an optional code block is provided, the new device context will be passed into the block as an
# argument and {#end} will be called automatically when the block terminates.
