+wxStaticPicture class
+by Wade Brainerd (wadeb@wadeb.com)
+
+Description:
+
+This class is an improved version of wxStaticBitmap.  
+
+Rather than using a native bitmap control, it uses DC operations to draw the
+control.  This makes its appearance more consistent across platforms, and
+allows for additional features.
+
+Features include:
+
+  wxStaticBitmap compatible API - drop-in replacement.  Image alignment - top,
+  left, bottom, right, center vertical and/or horizontal.
+  Image scaling - scale horizontally and/or vertically, justified scaling
+  (maintains image aspect ratio).
+
+Platforms tested:  
+
+  wxMSW
+  wxGTK
+  wxMac
+  
+Implementation notes:
+
+Under MSW wxWindows uses the operating system to do an optimized (potentially
+hardware accelerated) blit in wxDC::DrawBitmap.  This is usually fast enough to
+do image scaling without affecting the program's interactivity.  
+
+On wxMac and wxGTK however, wxDC::DrawBitmap implicitly calls wxImage::Scale 
+which is a much slower operation.  Therefore, on these platforms wxStaticPicture 
+caches the scaled image to make updates that don't change the image (overlapping 
+windows, etc.) faster.
