Add matching origin checks to checkSpecsMatch.
A simplification that removes the need to avoid unnecessary fatal errors.
This completes the rewrite to prevent the target spec. being updated when subsequent files are loaded.
Scale and resize are now implemented and all existing tests pass. The only changes to the tests are for updated messages. No generated .ktx2 files have been changed.
Fix: do not update target spec on subsequent input file reads. Things were only working because no code after the ktxTexture2 is created was dependent on the values in the target image spec. Upcoming work needs those values.
…known. Add --levels to help. Improve error messages.

Missing functionality from the legacy tool added so we can comfortably remove the legacy tools in 4.5. The following issues were discovered and fixed while adding the features: * The target imageSpec was being updated for every input file. This was only working because, until now, nothing had looked at the spec values that were being changed once the texture had been created. The fix is to make separate determineSourceColorSpace and determineTargetColorSpace functions. * An associated fix to the above is to move the checks for non-null transferFunctions to the use site with fatal errors thrown then if they are null. This avoids the need for second guessing to avoid the fatal errors when the transferFunctions will not be used. With this and the above fix, the code is now much more robust and clear. * Full help was missing --levels. * Full help had an incorrect statement regarding implicit color conversions dating from the transfer function work.
