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.

Poly2Tri-C is a library for generating, refining and rendering 2-Dimensional Constrained Delaunay Triangulations.

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.

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.

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.

This package provides the default set of brushes for MyPaint.

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.

This package provides the default set of brushes for MyPaint.

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.

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.

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.

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

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

GLU, or OpenGL Utility Library provides some higher-level functionality not provided by just OpenGL itself. Some of GLU's Features include: Scaling of 2D images and creation of mipmap pyramids, Transformation of object coordinates into device coordinates and vice versa, Support for NURBS surfaces, Support for tessellation of concave or bow tie polygonal primitives, Specialty transformation matrices for creating perspective and orthographic projections, positioning a camera, and selection/picking, Rendering of disk, cylinder, and sphere primitives, Interpreting OpenGL error values as ASCII text.

This is the last version of the mojoshader library with the glProgramViewportFlip before it was replaced with glProgramViewportInfo.

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.

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

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

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

GL2PS is a C library providing high quality vector output for any OpenGL application. GL2PS uses sorting algorithms capable of handling intersecting and stretched polygons, as well as non-manifold objects. GL2PS provides many features including advanced smooth shading and text rendering, culling of invisible primitives and mixed vector/bitmap output.

Piglit is a collection of automated tests for OpenGL and OpenCL implementations.

S2TC is a patent-free implementation of S3 Texture Compression (S3TC, also known as DXTn or DXTC) for Mesa.
