OpenGL applications should not depend on the Mesa drivers, since these are supposed to be loaded at runtime from /run/opengl-driver using the glvnd library. Furthermore, the drivers output has a large closure since it depends on LLVM. The only dependency from dev to drivers came from the xatracker pkg-config file. This commit moves this file into a new output called driversdev.

/** Packaging design:
|
|
- The basic mesa ($out) contains headers and libraries (GLU is in libGLU now).
|
|
This or the mesa attribute (which also contains GLU) are small (~ 2 MB, mostly headers)
|
|
and are designed to be the buildInput of other packages.
|
|
- DRI drivers are compiled into $drivers output, which is much bigger and
|
|
depends on LLVM. These should be searched at runtime in
|
|
"/run/opengl-driver{,-32}/lib/*" and so are kind-of impure (given by NixOS).
|
|
(I suppose on non-NixOS one would create the appropriate symlinks from there.)
|
|
- libOSMesa is in $osmesa (~4 MB)

|
|
The Mesa project began as an open-source implementation of the OpenGL
|
|
specification - a system for rendering interactive 3D graphics. Over the
|
|
years the project has grown to implement more graphics APIs, including
|
|
OpenGL ES (versions 1, 2, 3), OpenCL, OpenMAX, VDPAU, VA API, XvMC, and
|
|
Vulkan. A variety of device drivers allows the Mesa libraries to be used
|
|
in many different environments ranging from software emulation to
|
|
complete hardware acceleration for modern GPUs.
