Mitchell Richters 1900cf1fcc - Move Duke's getincangle() function to the backend, create Q16.16 variant (getincangleq16()) and replace Shadow Warrior's discrete implementations shared versions. ... * Need SW's input helpers available for Blood but therefore also need an angle delta function that does not seem to exist in Blood. * Realise that gamecontrol.h/cpp might not be the most appropriate place, but it's a shared location and these will go into binaryangle.h when its utilisation can be more realised. * Because SW's logic was reversed, in that param #1 was the new angle and param #2 was the current, all calls have been reversed. * By happenstance, also fixes an issue with multiple 180° turns in quick succession.		2020-09-20 16:21:13 +10:00
