(svn r12352) -Fix: Some callback-results were treated as 8 bit, when they were 15 bit, and vice versa.

Browse Source 
Var 0x7E procedure-results are always 15 bit.
  Callbacks 0x2A, 0x2C, 0x36 (sometimes), 0x39 and 0x145 are 15 bit.
  Non-varaction2-calculated callback-results are also affected by the 8bit masking.
