+Mesa 7.11 is a new development release.
+People who are concerned with stability and reliability should stick

+Mesa 7.11 implements the OpenGL 2.1 API, but the version reported by

+Some drivers don't support all the features required in OpenGL 2.1.

+
+
+<h2>Changes</h2>
+<ul>
+<li>The Windows MSVC project files have been removed.
+They haven't been maintained in quite a while.
+Building with SCons is an alternative.
+<li>Removed GL_SGI_texture_color_table support from swrast driver - the only
+driver that implemented it.

+ * ctx->Driver.TexImage2D = _mesa_store_teximage2d;
+ * ctx->Driver.TexImage3D = _mesa_store_teximage3d;

+ * Texture image processing is actually kind of complicated. We have to do:

+/** @file register_allocate.c
+ *
+ * Graph-coloring register allocator.
+ *
+ * The basic idea of graph coloring is to make a node in a graph for
+ * every thing that needs a register (color) number assigned, and make
+ * edges in the graph between nodes that interfere (can't be allocated
+ * to the same register at the same time).
+ *
+ * During the "simplify" process, any any node with fewer edges than
+ * there are registers means that that edge can get assigned a
+ * register regardless of what its neighbors choose, so that node is
+ * pushed on a stack and removed (with its edges) from the graph.
+ * That likely causes other nodes to become trivially colorable as well.
+ *
+ * Then during the "select" process, nodes are popped off of that
+ * stack, their edges restored, and assigned a color different from
+ * their neighbors. Because they were pushed on the stack only when
+ * they were trivially colorable, any color chosen won't interfere
+ * with the registers to be popped later.
+ *
+ * The downside to most graph coloring is that real hardware often has
+ * limitations, like registers that need to be allocated to a node in
+ * pairs, or aligned on some boundary. This implementation follows
+ * the paper "Retargetable Graph-Coloring Register Allocation for
+ * Irregular Architectures" by Johan Runeson and Sven-Olof Nyström.
+ *
+ * In this system, there are register classes each containing various
+ * registers, and registers may interfere with other registers. For
+ * example, one might have a class of base registers, and a class of
+ * aligned register pairs that would each interfere with their pair of
+ * the base registers. Each node has a register class it needs to be
+ * assigned to. Define p(B) to be the size of register class B, and
+ * q(B,C) to be the number of registers in B that the worst choice
+ * register in C could conflict with. Then, this system replaces the
+ * basic graph coloring test of "fewer edges from this node than there
+ * are registers" with "For this node of class B, the sum of q(B,C)
+ * for each neighbor node of class C is less than pB".
+ *
+ * A nice feature of the pq test is that q(B,C) can be computed once
+ * up front and stored in a 2-dimensional array, so that the cost of
+ * coloring a node is constant with the number of registers. We do
+ * this during ra_set_finalize().
