[TPReal]

• Normalising a vector shortwer than epsilon is fine, no need to set minimal length.
• Normalising a vector of zero length unnecessarily multiplied the components by a factor - the components are zero anyway.
• Renamed engine_math_map_clamp_out to engine_math_map_clamp as it doesn't matter if it the in or out values that are clamped, and changed to clamping the in values to avoid some multiplication and division when possible.
• Actually used the engine_math_map_clamp function in some places that did clamping and mapping separately.

If you could, let's switch out the ternaries for if-statements. That's the one consistent code style aspect that is consistent (except for the min and max MACROs).

Done. Don't understand why you don't like the ternary though :)
