39// wxWindows uses the Microsoft convention that the origin is the UPPER left.
40// Native OS/2 however in the GPI and PM define the origin as the LOWER left.
41// In order to map OS/2 GPI/PM y coordinates to wxWindows coordinates we must
42// perform the following transformation:
43//
44// Parent object height: POBJHEIGHT
45// Desried origin: WXORIGINY
46// Object to place's height: OBJHEIGHT
47//
48// To get the OS2 position from the wxWindows one:
49//
50// OS2Y = POBJHEIGHT - (WXORIGINY + OBJHEIGHT)
51//
52// For OS/2 wxDC's we will always determine m_vRclPaint as the size of the
53// OS/2 Presentation Space associated with the device context. y is the
54// desired application's y coordinate of the origin in wxWindows space.
55// objy is the height of the object we are going to draw.
56//
57#define OS2Y(y, objy) ((m_vRclPaint.yTop - m_vRclPaint.yBottom) - (y + objy))
