The `ProjectionTransform` object has no trivial copy-assignment constructor.
This results in the following warning on `gcc (Ubuntu 13.2.0-23ubuntu4) 13.2.0`:
```
/.../blender-git/blender/intern/cycles/kernel/../util/projection.h: In function ‘ccl::ProjectionTransform ccl::projection_inverse(ProjectionTransform)’:
/.../blender-git/blender/intern/cycles/kernel/../util/projection.h:219:9: warning: ‘void* memcpy(void*, const void*, size_t)’ writing to an object of type ‘ccl::ProjectionTransform’ {aka ‘struct ccl::ProjectionTransform’} with no trivial copy-assignment; use copy-assignment or copy-initialization instead [-Wclass-memaccess]

```
To fix the warning, cast the pointer to `(void *)`.
