Rostislav Pehlivanov	8248b51e0b	diracdec: add support for 12 bit videos The DSP lacked a function needed to convert signed to unsigned. This was ignored when originally adding support and templating for bit depths greater than 8. The 10 bit function was used for 12 bit pictures and resulted in an improper conversion.
