io (input / output e.g. print)
================================================================================

Header: cglm/io.h

There are some built-in print functions which may save your time,
especially for debugging.

All functions accept **FILE** parameter which makes very flexible.
You can even print it to file on disk.

In general you will want to print them to console to see results.
You can use **stdout** and **stderr** to write results to console.
Some programs may occupy **stdout** but you can still use **stderr**.
Using **stderr** is suggested.

Example to print mat4 matrix:

.. code-block:: c

   mat4 transform;
   /* ... */
   glm_mat4_print(transform, stderr);

**NOTE:** print functions use **%0.4f** precision if you need more
(you probably will in some cases), you can change it temporary.
cglm may provide precision parameter in the future
