Branch based on shader model

Use SHADER_TARGET to make shader behaviour conditional on the shader model.

SHADER_TARGET
is defined to a numeric value that matches the Shader target compilation model (that is, matching 
#pragma target
directive). For example, 
SHADER_TARGET
is 
30
when compiling into Shader model 3.0. You can use it in Shader code to do conditional checks. For example:
#if SHADER_TARGET < 30    // less than Shader model 3.0:    // very limited Shader capabilities, do some approximation#else    // decent capabilities, do a better thing#endif
