I submitted an official bug through the proper channel but didn't get any kind of reference number or anything to reference my submission in the future.
Here is the function which is a reference to API callback "AVAnnotHandlerDrawExProc". The numbers for each structure here are identical when switching between high-res/low-res on the same Retina Display yet they are displayed in the wrong position and at the wrong size in high-res mode.
//AcroFmDrawEx
static ACCB1 void ACCB2 AcroFmDrawEx( AVAnnotHandler handler, PDAnnot pdAnnot, AVPageView pageView, AVRect* pRect )
{
void* port = AVPageViewAcquireMachinePort(pageView);
ASFixedRect userPDAnnot;
AVRect deviceRect, aperture;
Rect dstRect;
PDAnnotGetRect( pdAnnot, &userPDAnnot );
AVPageViewRectToDevice(pageView, &userPDAnnot, &deviceRect);
AVPageViewGetAperture( pageView, &aperture );
dstRect.left = deviceRect.left - aperture.left;
dstRect.top = deviceRect.top - aperture.top;
dstRect.right = deviceRect.right - aperture.left;
dstRect.bottom = deviceRect.bottom - aperture.top;
CopyBits(GetPortBitMapForCopyBits(port), GetPortBitMapForCopyBits(port), &dstRect, &dstRect, srcXor, 0);
AVPageViewReleaseMachinePort(pageView, port);
}
