+This module will do surgery on the wx.DC class in wxPython 2.5.1.5 to
+make it act like the wx.DC class in later versions will. To use this
+module simply import it in one of your program's modules before you
+use any DC's. It does its work upon import and then is done.
+
+This module will *only* do something if it is imported in an app
+running on wxPython 2.5.1.5, for all other versions it will do
+nothing. This means that you can include it with your application and
+then if your user is on 2.5.1.5 the DC methods will be updated, but if
+they are on a newer version (or an older one for that matter) then
+nothing will be done and your code using DCs will still be compatible.
+
+So what does it do? In a nutshell, the old 2.4.x style of method
+names, where the 'normal' name takes separate parameters for x, y,
+width and height will be restored, and the new methods that take
+wx.Point and/or wx.Size (which can also be converted from 2-element
+sequences) will be given new non-default method names. The 2.5.1.5
+'XY' style names will be removed. The new names for the 'Point/Size'
+methods are:
+
+ * BlitPointSize
+ * CrossHairPoint
+ * DrawArcPoint
+ * DrawBitmapPoint
+ * DrawCheckMarkRect
+ * DrawCirclePoint
+ * DrawEllipsePointSize
+ * DrawEllipticArcPointSize
+ * DrawIconPoint
+ * DrawLinePoint
+ * DrawPointPoint
+ * DrawRectanglePointSize
+ * DrawRotatedTextPoint
+ * DrawRoundedRectanglePointSize
+ * DrawTextPoint
+ * FloodFillPoint
+ * GetPixelPoint
+ * SetClippingRegionPointSize
+
+Please note that only the names that you access the methods by will be
+changed. The names used in docstrings as well as the names used to
+call the extenaion functions and the names used when raising
+exceptions will still use the old names. (Of course once a new
+version of wxPython has been built with this new style then this will
+no longer apply. The new names will be the real names.) For
+example::
+
+ Traceback (most recent call last):
+ File "/usr/lib/python2.3/site-packages/wx/lib/buttons.py", line 272, in OnPaint
+ self.DrawBezel(dc, x1, y1, x2, y2)
+ File "/usr/lib/python2.3/site-packages/wx/lib/buttons.py", line 220, in DrawBezel
+ dc.DrawLine((x1+i, y1), (x1+i, y2-i))
+ File "/usr/lib/python2.3/site-packages/wx/gdi.py", line 2293, in DrawLine
+ return _gdi.DC_DrawLineXY(*args, **kwargs)
+ TypeError: DC_DrawLineXY() takes exactly 5 arguments (3 given)
+
+
+WARNING: If you import this module then the wx.DC class will be
+ changed for the entire application, so if you use code from
+ the wx.lib package (or 3rd party modules that have already
+ been converted to the doomed 2.5.1.5 implementaion of the DC
+ Draw methods) then that code will break as shown above. This
+ is an all-or-nothing fix, (just like the next version of
+ wxPython will be,) so you *will* need to do something to
+ resolve this situation if you run into it. The best thing to
+ do of course is to correct the library module to work with
+ the corrected DC semantics and then send me a patch, although
+ it probably won't be too long before the library modules are
+ updated in CVS so you could get a copy of them there.
