#34

It seems as if I removed the newlines at the end of the files, due to unix encoding. Was worried that would happen. Let me know if thats a problem.

Good PR, just one thing:

• The mat3 and mat4 types do not specify size, it is not guaranteed that these are an array, simply a pointer to a float, or an array that does not match the needed size. typedef int array_type_example[5]; array_type_example my_array = {1,2,3,4,5}.
• It may also be a good idea to check if the array is NULL, but I can implement that as I want to rework assertions in Muzzle.

What exactly should be done if the array is NULL? Should I check the entire array's size for NULL?

No, just the pointer. Also use log_status() for Error Logging. Again I can do that part. I just need the sized types

Everything Looks good!
