USE flags

• cpu_flags_x86_sse2 - Use the SSE2 instruction set
• debug - Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
• doc - Add extra documentation (API, Javadoc, etc). It is recommended to enable per package instead of globally
• openexr - Support for the OpenEXR graphics file format
• openmp - Build support for the OpenMP (support parallel computing), requires >=sys-devel/gcc-4.2 built with USE="openmp"
• tcmalloc - Use the dev-util/google-perftools libraries to replace the malloc() implementation with a possibly faster one
