Defines an integer constant value, which should be loaded any time a shader is set to a device.
|defi dst, integerValue|
- dst is the destination register.
- integerValue is a constant integer value.

The defi instruction defines a shader constant whose value is loaded anytime a shader is set to a device. These are called immediate constants. Immediate constants take precedence over constants set by the API method SetPixelShaderConstantB.
There are two ways to set a constant in a shader.
- Use defi to define the constant directly inside a shader.
- Use the API methods to set a constant.
