MrG is is a C API for creating user interfaces. It can be used as an application writing environment or as an interactive canvas for part of a larger interface.

This package provides the default set of brushes for MyPaint.

GEGL (Generic Graphics Library) provides infrastructure to do demand based cached non destructive image editing on larger than RAM buffers.

This package provides resynthesizer plugins for GIMP, which encompasses tools for healing selections (content-aware fill), enlarging the canvas and healing the border, increasing the resolution while adding detail, and transferring the style of an image.

Babl is a dynamic, any-to-any pixel format translation library. It allows converting between different methods of storing pixels, known as pixel formats, that have different bit depths and other data representations, color models, and component permutations.

A vocabulary to formulate new pixel formats from existing primitives is provided, as well as a framework to add new color models and data types.

Libmypaint, also called "brushlib", is a library for making brushstrokes which is used by MyPaint and GIMP.

GIMP is an application for image manipulation tasks such as photo retouching, composition and authoring. It supports all common image formats as well as specialized ones. It features a highly customizable interface that is extensible via a plugin system.

GKrellM is a single process stack of system monitors which supports applying themes to match its appearance to your window manager, Gtk, or any other theme.

The OpenGL Extension Wrangler Library (GLEW) is a C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file.

Guile-OpenGL is a library for Guile that provides bindings to the OpenGL graphics API.

GLFW is a library for OpenGL, OpenGL ES and Vulkan development for desktop computers. It provides a simple API for creating windows, contexts and surfaces, receiving input and events.

Mesa is a free implementation of the OpenGL and Vulkan specifications - systems for rendering interactive 3D graphics. A variety of device drivers allows Mesa to be used in many different environments ranging from software emulation to complete hardware acceleration for modern GPUs.

A library for handling OpenGL function pointer management.

libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API calls between multiple vendors. It allows multiple drivers from different vendors to coexist on the same file system, and determines which vendor to dispatch each API call to at runtime.

Both GLX and EGL are supported, in any combination with OpenGL and OpenGL ES.

NanoVG is an antialiased vector graphics rendering library for OpenGL. It is aimed for building scalable user interfaces and visualizations.

libopenglrecorder is a library allowing optional async readback OpenGL frame buffer with optional audio recording. It will do video and audio encoding together.

Glad uses the official Khronos XML specifications to generate a GL/GLES/EGL/GLX/WGL loader tailored for specific requirements.

Freeglut is a completely Free/OpenSourced alternative to the OpenGL Utility Toolkit (GLUT) library. GLUT was originally written by Mark Kilgard to support the sample programs in the second edition OpenGL RedBook. Since then, GLUT has been used in a wide variety of practical applications because it is simple, widely available and highly portable.

GLUT (and hence freeglut) allows the user to create and manage windows containing OpenGL contexts on a wide range of platforms and also read the mouse, keyboard and joystick functions. Freeglut is released under the X-Consortium license.

The mesa-utils package contains several utility tools for Mesa: eglinfo, glxdemo, glxgears, glxheads, and glxinfo.

FTGL is a font rendering library for OpenGL applications. Supported rendering modes are: Bitmaps, Anti-aliased pixmaps, Texture maps, Outlines, Polygon meshes, and Extruded polygon meshes.

Waffle is a library that allows one to defer selection of an OpenGL API and a window system until runtime.
