st/nine: Cleaning code for vs temporaries
This has been a real mess up to now: the temporaries were allocated once, and shared after that between the different parts of the code. To help maintaining the code, the temporaries are now allocated and released on need. As surprising as it could be, this patch, which was supposed to introduce no behaviour change, actually solved a visual bug observed on a sample program. This was due to ureg_normalize3 polluting a temporary variable. Signed-off-by: Axel Davy <[email protected]>
