Normally Mesa (and OpenGL) records but does not notify the user of
errors. It is up to the application to call
<code>glGetError</code> to check for errors. Mesa supports an
- environment variable, MESA_DEBUG, to help with debugging. If
- MESA_DEBUG is defined, a message will be printed to stdout whenever
- an error occurs.

- More extensive error checking is done when Mesa is compiled with the
- DEBUG symbol defined. You'll have to edit the Make-config file and
- add -DDEBUG to the CFLAGS line for your system configuration. You may
- also want to replace any optimization flags with the -g flag so you can
- use your debugger. After you've edited Make-config type 'make clean'
- before recompiling.

- In your debugger you can set a breakpoint in _mesa_error() to trap Mesa

There is a display list printing/debugging facility. See the end of
