Freetype is a part of official QT distro. Is it possible to include it into QT/2 as well?

It seems that value of 32768 bytes for default thread stack size is too small. This cause program photoproc trap due to low stack in 2-nd thread. I propose to increase it to 2Mb (0x200000) value.

If we have a QApplication instance created on the stack in main() (a very common practice for 99% of Qt apps), then an attempt to call the exit() function from stdlib will produce an application trap with a popuplog entry (SYS3170/c0010001, most likely in DOSCALL1.DLL).

A simple example to reproduce:

#include <qapplication.h>
#include <stdlib.h>
int main (int argc, char **argv)
{
    QApplication a (argc, argv);
    exit (-1);
}

From what I've already found, this happens when a global QFontCache (internal QObject subclass) instance is being destroyed (by a static func from the exit list). It is created as a child of QApplication, so its QObject desctructor calls parentObject->removeChild (this); but for some reason the vtable of the QApplocation instance is already corrupted by that time (but no QApplocation destructor has been called yet!).
