Initial commit of libAgl2 using Pixelflinger2 in external/mesa3d
Somewhat functional, refer to README for details.
Need to enable Android.mk to build.
It builds libGLES_android.so, which needs to replace
the one in system/lib/egl built by libagl.

+libAgl2 provides software GL ES 2.0 implementation using Pixelflinger2 in external/mesa3d
+
+To build, enable Android.mk, which builds libGLES_android.so, then replace the one built from libAgl in system/lib/egl.
+ES 1.0 functions are not implemented and will cause exit, so do not setprop debug.egl.hw 0 until launcher is loaded.
+
+All functions have little to none error checking.
+Not thread safe, Pixelflinger2 uses some static data.
+
+Most shader functions are implemented, however, most Get* functions for shaders/programs/uniforms/attribs are not.
+No name system for shaders/programs, just using the pointers as names.
+
+Basic glTexImage2D, glTexSubImage2D, glCopyImage2D and glCopySubImage2D are implemented, with a range of 8/16/24/32bpp formats.
+Cube map support is minimal. No mipmapping.
+TexParameter is mostly implemented, supports texcoord wrap modes, and only linear for both min and mag, or nearest for both min and mag filtering.
+Texture names are implemented, but bad.
+
+Frame buffer and render buffers are not implemented.
+
+Depth and stencil are implemented, but not tested.
+Blending seems to work.
+Colorbuffer supports RGBA_8888 and RGB_565.
+
+Vertex buffer objects are implemented.
+Some GL_TRIANGLES and GL_TRIANGLE_STRIPS modes for glDrawArrays and glDrawElements are implemented, but vertex order is probably wrong so culling is disabled.
+
+Basic apps should work, and some libhwui should work, except for frame buffer operations, which will cause exit.
