+ * display, not the Mesa host.
+ * The color-to-pixel encoding for True/DirectColor must be done
+ * according to the display's visual red_mask, green_mask, and blue_mask.
+ * If XPutPixel is used to put a pixel into an XImage then XPutPixel will
+ * do byte swapping if needed.  If one wants to directly "poke" the pixel
+ * into the XImage's buffer then the pixel must be byte swapped first.

+/* Sample Usage:
+
+In addition to the usual X calls to select a visual, create a colormap
+and create a window, you must do the following to use the X/Mesa interface:
+
+1. Call XMesaCreateVisual() to make an XMesaVisual from an XVisualInfo.
+
+2. Call XMesaCreateContext() to create an X/Mesa rendering context, given
+   the XMesaVisual.
+
+3. Call XMesaCreateWindowBuffer() to create an XMesaBuffer from an X window
+   and XMesaVisual.
+
+4. Call XMesaMakeCurrent() to bind the XMesaBuffer to an XMesaContext and
+   to make the context the current one.
+
+5. Make gl* calls to render your graphics.
+
+6. Use XMesaSwapBuffers() when double buffering to swap front/back buffers.
+
+7. Before the X window is destroyed, call XMesaDestroyBuffer().
+
+8. Before exiting, call XMesaDestroyVisual and XMesaDestroyContext.

+This directory contains Python bindings to Gallium3D. It looks like a state
+tracker from the pipe driver perspective, and it looks like a pipe driver from
+the python script perspective.
+
+
+To build you'll need:
+* Python (with development packages)
+* SCons
+* SWIG
+* Python Imaging Library with TK support (for the samples)
+
+Invoke scons on the top dir as
+ 
+ scons statetrackers=python
+
+To use do
+
+ export PYTHONPATH=build/XXXX-XXXX-XXXX/gallium/state_trackers/python
+
+and then try running
+
+  python src/gallium/state_trackers/python/samples/tri.py
+
+which should show a triangle.
+
+
+This is still work in progress:
+- errors are not handled properly and almost always result in crash
+- state atoms with array members are awkward to set
+- there no efficient way to view images
