+2005-09-27 Ian Romanick <idr@us.ibm.com>
+
+ * indirect.c:
+ Remove __glEvalComputeK. It is no longer used.
+
+
+2005-04-09 Alexander Gottwald <ago at freedesktop dot org>
+
+ * indirect.c:
+ Fix passing of non-RGB visuals. The old code did not initialize the
+ structure properly which lead to a crash in 8bpp mode
+
+2005-03-01 Alexander Gottwald <ago at freedesktop dot org>
+
+ * indirect.c:
+ * glwindows.h:
+ If a context is already attached copy it instead of reattaching to keep
+ displaylists and share displaylists
+ Enable tracing of often called functions with GLWIN_ENABLE_TRACE
+ ForceCurrent is a no-op now
+
+2005-02-02 Alexander Gottwald <ago at freedesktop dot org>
+
+ * Imakefile:
+ Bugzilla #1866 (https://bugs.freedesktop.org/show_bug.cgi?id=1866)
+ attachment #1819 (https://bugs.freedesktop.org/attachment.cgi?id=1819):
+ Define APIENTRY on windows to prevent <GL/gl.h> from loading <windows.h>
+
+2005-02-02 Alexander Gottwald <ago at freedesktop dot org>
+
+ * glwrap.c:
+ * glwindows.h:
+ Bugzilla #1866 (https://bugs.freedesktop.org/show_bug.cgi?id=1866)
+ attachment #1818 (https://bugs.freedesktop.org/attachment.cgi?id=1818):
+ Include Xwindows.h before GL/gl.h to prevent loading windows.h which
+ pollutes our namespace with some symbols.
+
+2005-01-27 Alexander Gottwald <ago at freedesktop dot org>
+
+ * glwrap.c:
+ Functions like glGenTextures and glBindTexture are in OpenGL 1.1
+ and can be resolved at linktime.
+
+2004-11-15 Alexander Gottwald <ago at freedesktop dot org>
+
+ * indirect.c:
+ Bugzilla #1802, http://freedesktop.org/bugzilla/show_bug.cgi?id=1802
+ Added mingw (Win32) port
+
+2004-08-13 Alexander Gottwald <ago@freedesktop.org>
+
+ * Imakefile: Added $(MESASRCDIR)/src/mesa/glapi to INCLUDES.
+ Removed $(SERVERSRC)/mi from INCLUDES.
+ Rearranged INCLUDES for better readability.
+ * glwindows.h: Removed mipointrst.h and miscstruct.h from #include
+ since they are not used anymore.
+
+2004-05-27 Alexander Gottwald <ago@freedesktop.org>
+
+ * glwindows.h: write current function and line in debug output
+ * indirect.c: moved actual setup and creation of windows GL context to
+ glWinCreateContextReal.
+ * indirect.c (glWinCreateContext): Deferred context creation to attach.
+ * indirect.c (glWinMakeCurrent): Check if context is NULL. Fixes segfault.
