These extensions allow an application to make a context current by
passing EGL_NO_SURFACE for the write and read surface in the call to
eglMakeCurrent. The motivation is that applications that only want to
render to client API targets (such as OpenGL framebuffer objects)
should not need to create a throw-away EGL surface just to get a
current context.

I am not sure how to properly handle flat shading regarding
non color parameter to fragment shader. It seems we should
still interpolate non color using linear interpolation and
flat shade only apply to color.

Otherwise, we lose DEBUG, which causes mtypes.h to set NDEBUG, which
causes assertions to not happen, which is no fun for anyone.

Split hw vs pipe states creation handling as hw states group doesn't
match pipe state group exactly. Right now be dumb about that and
rebuild all hw states on each draw call. More optimization on that
side coming.

The type signatures were completely backwards.

There's no need to use an ir_expression; we have a handy C function.

This shouldn't be required since dot is only defined for floating point
types, even in GLSL 4.0.

These builtin functions are represented by ir_expression_operations, so
we can just create one of those and ask for its value.
|
|
These always return zero (the derivative of a constant).
