+// wxWidgets uses the Microsoft convention that the origin is the UPPER left.
+// Native OS/2 however in the GPI and PM define the origin as the LOWER left.
+// In order to map OS/2 GPI/PM y coordinates to wxWidgets coordinates we must
+// perform the following transformation:
+//
+// Parent object height: POBJHEIGHT
+// Desried origin: WXORIGINY
+// Object to place's height: OBJHEIGHT
+//
+// To get the OS2 position from the wxWidgets one:
+//
+// OS2Y = POBJHEIGHT - (WXORIGINY + OBJHEIGHT)
+//
+// For OS/2 wxDC's we will always determine m_vRclPaint as the size of the
+// OS/2 Presentation Space associated with the device context. y is the
+// desired application's y coordinate of the origin in wxWidgets space.
+// objy is the height of the object we are going to draw.
+//
+#define OS2Y(y, objy) ((m_vRclPaint.yTop - m_vRclPaint.yBottom) - (y + objy))
