While Linux was not an original goal of the project, it should still be supported out of the box. Therefore a number of changes are contained in this changeset: - All C++ .h files were renamed to .hpp. - All C includes (<....h>) were replaced with C++ includes (<c...>) and missing includes were added. - std::memset and std::memcpy was replaced with memset and memcpy. - All anonymous structs were removed where necessary. - `extern "C"` was removed where it wasn't needed. - #pragma warning was placed behind an #ifdef _MSC_VER - The macros for `min`, `max` and `clamp` were removed as they were not used. - `-fpedantic` was added to the GCC flags for bitmask support. - `gs::rendertarget_op` is now declared before use. - std::exception(const char*) was replaced with std::runtime_error(const char*). - Added aligned_alloc and aligned_free macros for GCC and MSVC support. - Replaced use of `sprintf_s` with `snprintf`. - Placed additional guards around windows only code. Additonally some changes were made that do not affect Linux: - `NOMINMAX` and `NOINOUT` were removed. Fixes: #27 Fixes: #13
