This version only fixes a couple a major bugs introduced in GLM 0.9.2.2. Half based vector types have been fixed on GCC 4.4 and below, missing l-value swizzle operations added and a couple of other bugs squeezed down.
</p><p>
Finally, all the Visual C++ /W4 warnings should have been removed. However, for this to happen, it is required to build with the Visual C++ language extension disabled (/Za).

<paragraph>
Half based vector types have been fixed on GCC 4.4 and below, missing l-value swizzle operations added and a couple of other bugs squeezed down.
</paragraph>
<paragraph>
Finally, all the Visual C++ /W4 warnings should have been removed. However, for this to happen, it is required to build with the Visual C++ language extension disabled (/Za).
