When flushing a fixed-function or arbfp material it would always call
disable_glsl to try to get rid of the previous GLSL shader. This is
needed even if current_use_program_type is not GLSL because if an
application calls cogl_program_uniform then Cogl will have to bind the
program to set the uniform. If this happens then it won't update
current_use_program_type presumably because the enabled state of arbfp
is still valid.
The problem was that disable_glsl would only select program zero when
the current_use_program_type is set to GLSL which wouldn't be the case
if cogl_program_uniform was called. This patch changes it to just
directly call _cogl_gl_use_program_wrapper(0) instead of having a
separate disable_glsl function. The current program is cached in the
cogl context anyway so it shouldn't cause any extra unnecessary GL
calls.

The simple key press example in the cookbook used a brittle
and incorrect switch statement to test modifier values. Instead,
use logical "&" of the state with the modifiers we're interested
in to check which keys were pressed.

g_ascii_dtostr was being used in four separate arguments to
g_string_append_printf but all invocations of it were using the same
buffer. This would end up with all of the arguments having the same
value which would depend on whichever order the compiler evaluates
them in. This patches changes it to use a multi-dimensional array and
a loop to fill in the separate buffers.

The cookbook should also include fully functional code examples. We can
even XInclude them into the docbook XML itself.
The examples should be built with the coobook, so that we can always
make sure they are up to date.
The ARBfp programs are created with a printf() wrapper, which usually
fails in non-en locales as soon as you start throwing things like
floating point values in the mix.
We should use the g_ascii_dtostr() function which places a double into a
string buffer in a locale-independent way.

Explains how to make an actor transparent so that other actors
are visible through it.
Also explains a bit more generally about opacity and how
it's computed from the actor, container, and color; and how actor
visibility is affected by depth (fog) and depth order.
