librnd 3.1.1 ~~~~~~~~~~~~ 3.1.1 implements hid_gtk4_gl, which is a fully working GUI HID with gtk4.4 or newer, using VAO based opengl rendering. The new HID does not change library API so it does not warrant a new minor version number. All applications using librnd can automatically use gtk4 now (even without the app recompiled). Besides the new opengl and gtk4 code and related refactoring of gtk and gl plugins, this release also features a lot of minor bugfixes.
