[Qt-creator] Qt Creator 3.4 binaries will be compiled with MSVC 2013 (dynamic opengl)

[Henry Skoglund]

Hi, couldn't resist taking you up on that XP claim :-)

I tested Qt Creator 3.3.81 built morning of March 30:

* On my XP machine: works fine (no patching required!)
* Windows 10 latest preview: works fine (future proof)
* Windows XP in Virtual Box 4.3.10: works fine
* Windows XP in VMWare Fusion 6.0.5: works fine
* Windows XP in VMWare Workstation 11.1.0: crashes with illegal 
instruction in opengl32sw.dll :-( The cure is to delete that file 
opengl32sw.dll and try again, then Qt Creator works, except of course 
for the Welcome plugin which is not so welcoming)

So why the snag in the VMWare Workstation XP? Well I ran qtdiag.exe (BTW 
what an excellent program that is, has no pretty UI but in my mind it's 
part of the real gold in Qt) turns out in both VMWare cases it's the 
same vmx_fb.dll that's used, for the XP in Fusion it returns LibGL 
vendor VMWare Inc. format version 2.0, which seems kosher for 
opengl32sw.dll. But for the XP in Workstation 11 it returns LibGL vendor 
Microsoft Corp Generic GDI format version 1.1, and that's probably why 
opengl32sw.dll goes haywire and has to be taken out behind the barn and 
shot.

+ also for now installing the MSVC2013 dlls into the bowels of Windows, 
the vanilla Qt 5.4.1 installs them alongside qtcreator.exe and as you 
know this is heavily frowned upon by Microsoft. (Unless of course you 
are Microsoft, in that case you can grant yourself an exemption from 
this rule like when installing the new Visual C++ Tools/Windows 10 Kit.)

P.S. BTW saw that 3.3.81 brings along Timeline.dll, is that a new 
feature (QML profiler stuff)?
