Remove the "If only executable code is distributed..." paragraph from
the license text. Everything now uses a normal MIT license.
The only code from Khronos that's included in libglvnd is the EGL/GL
header and XML files, which do not contain that paragraph.
Fixes https://gitlab.freedesktop.org/glvnd/libglvnd/-/issues/221
Added a dispatch handler for glXCreateContextAttribsARB. It'll look for a
GLX_SCREEN attribute first if the caller provides one, and then the GLXFBConfig
handle if the caller doesn't.
Two header files (libglxabi.h and GLdispatchABI.h) are public -- intended to be
used by vendor libraries, while the other headers are all internal to libglvnd.
Move the public header files to a new directory, include/glvnd.
Add a makefile so that the public headers are installed by make install.
Added dispatch functions to libGLX for glXImportContextEXT and
glXFreeContextEXT, since both of them are difficult to implement as a dispatch
function from a vendor library.
Since glXImportContextEXT doesn't take any parameters that directly specify a
screen, it will query the server manually to figure out a screen number.
Removed the __GLX14EntryPoints structure from the vendor library ABI. Instead,
libGLX will use the getProcAddress callback to look up each function after
loading the library.
Moved the contents of __GLXvendorCallbacks into __GLXapiImports.
Changed __GLXdispatchTableStatic to be a separate struct from __GLXapiImports.
It now contains all of the GLX 1.4 function pointers, replacing __GLX14EntryPoints.
- libglxabipriv.h: This is a simple wrapper around libglxabi.h which
defines the static dispatch table to be the same as the set of
functions exported by the vendor (they could potentially differ).
- libglxcurrent.h: This defines a current "API state" struct which
encapsulates the API library's knowledge of the current display,
read/draw drawables, dispatch tables, and vendor (owning the current
context). The glXGetCurrent*() functions are implemented by
retrieving various fields from this API state.
- libglxmapping.h: This defines a "vendor info" struct which contains
information about a loaded vendor. It also provides accessor functions
for retrieving the dispatch table given a screen, and functions for
adding/removing mappings from various keys (Context, FBConfig,
Drawable) to screens.
- libglx.c: Replace the dummy GetStaticDispatch() function with calls to
the API in libglxmapping.h to retrieve the right dispatch table.
