// If we are inside a code resource, we have two problems.

// First, our machine code doesn't yet know where in RAM it is located, so things

// will crash as soon as we call a function or access a global variable.

// The following call, part of libretro, fixes that:

// global variables. If we acces "qd.", we'll get our own copy, which QuickDraw knows

// nothing about. So, let's get a pointer to the real thing:
|
|
QDGlobalsPtr qdPtr = (QDGlobalsPtr)( (*(Ptr*)LMGetCurrentA5()) + 4 - sizeof(QDGlobals) );

// alternatively, we could just avoid accessing QuickDraw globals. In our case, that would mean

// using GetPort instead of qdPtr->thePort, and not using qdPtr->white and qdPtr->ltGray.
