Cover All Types in Angle Test

[threeal]

Cover every type (float, double, int, etc.) during Angle test. Some solution is by using combination of function macros as follows:

#define FUNCTION(TYPE) \
{ \
  /* some code */ \
}

#define ITERATE_ALL_TYPES(FUNCTION) \
{ \
  FUNCTION(float) \
  FUNCTION(double) \
  FUNCTION(int) \
  /* etc. */ \
}

Or by passing generic functions, or lambdas.
