Campbell Barton 67b74f96da - property sensor was converting floating point values to text then back to float - for floating point properties.
- IntValue's GetNumber() was convert int -> float -> double.
- BL_Shader was using STR_String rather then char*, where most callers had a char*, use a char* to avoid STR_String conversion-and-alloc on shader access.
