Incorrect/invalid KTX key-value data

The KTX specification recommends the use of a key KTXorientation to inform clients how to interpret the image data. However PVRTexTool seems to be generating KTX files with the key KTXOrientation (the key names should be considered case sensitive).

This appears to be at least one cause of this bug: https://github.com/KhronosGroup/KTX-Software/issues/106

Many thanks for reporting this bug in PVRTexTool. I have submitted issue 88479 and we will get it fixed shortly.

Thanks.

Carlos.
