Fix heap buffer overflow in Cycles IES parser The IES parser in Cycles would lead to heap buffer overflow error when non-supported or invalid data is provided to it. The error was caused by the way how stirng is copied to vector skipping the last null-terminator. Later C-style string utilities are used for parsing, and they expect the data to be null-terminated. It is unclear why data needs to be stored as vector: storing it as string simplifies initialization. Easiest to reproduce the issue is to use Blender build with address sanitizer enabled.

Cleanup: Cycles: Use gtest header instead of Blender test header To avoid conflicts with glog logging macros, and because there is just no need to have this dependency. Pull Request: https://projects.blender.org/blender/blender/pulls/143719 2025-07-31 19:46:54 +02:00			`#include <gtest/gtest.h>`
