# drawing interface operations
#
# History:
# 1996-04-13 fl   Created (experimental)
# 1996-08-07 fl   Filled polygons, ellipses.
# 1996-08-13 fl   Added text support
# 1998-06-28 fl   Handle I and F images
# 1998-12-29 fl   Added arc; use arc primitive to draw ellipses
# 1999-01-10 fl   Added shape stuff (experimental)
# 1999-02-06 fl   Added bitmap support
# 1999-02-11 fl   Changed all primitives to take options
# 1999-02-20 fl   Fixed backwards compatibility
# 2000-10-12 fl   Copy on write, when necessary
# 2001-02-18 fl   Use default ink for bitmap/text also in fill mode
# 2002-10-24 fl   Added support for CSS-style color strings
# 2002-12-10 fl   Added experimental support for RGBA-on-RGB drawing
# 2002-12-11 fl   Refactored low-level drawing API (work in progress)
# 2004-08-26 fl   Made Draw() a factory function, added getdraw() support
# 2004-09-04 fl   Added width support to line primitive
# 2004-09-10 fl   Added font mode handling
# 2006-06-19 fl   Added font bearing support (getmask2)
