/**
Introduction:
Holds a description of the textures, samplers, shaders, parameters,
and passes necessary for rendering this effect using one method.
Concepts:
Techniques hold all the necessary elements required to render an effect.
Each effect can contain many techniques, each of which describes a
different method for rendering that effect. There are three different
scenarios for which techniques are commonly used:
� One technique might describe a high-LOD version while a second technique
describes a low-LOD version of the same effect.
� Describe an effect in different ways and use validation tools in the FX
Runtime to find the most efficient version of an effect for an unknown
device that uses a standard API.
� Describe an effect under different game states, for example, a daytime
and a nighttime technique, a normal technique, and a "magic-is-enabled"
technique.
Parent elements:
profile_CG, profile_COMMON, profile_GLSL, profile_GLES
Child Elements
Child elements vary by profile. See the parent element main entries
for details. The following list summarizes valid child elements. The
child elements must appear in the following order if present, with the
following exceptions: <code> and <include>; <newparam>, <setparam>,
and <image> are choices, can appear in any order in that position;
<blinn>, <constant>, <lambert>, <phong> are choices, can appear in any
order in that position:
Name profile_CG profile_COMMON profile_GLES profile_GLSL Occurrences
<asset> yes yes yes - 0 or 1
<annotate> yes - yes yes 0 or more
<include> yes - - yes 0 or more
<code> yes - - yes 0 or more
<newparam> yes yes yes yes 0 or more
<setparam> yes - yes yes 0 or more
