formZ background shader callbacks function set version.

Description

Function set for background shaders. The functions in this set need to be supplied by the plugin or script to implement a background and environment shader.
The main shader function is the callback. It is expected to compute the color of a background pixel. Typically, the two dimensional coordinate of a background pixel is used to compute the pattern of the background. This pixel coordinate can be retrieved by the function call ().
There are required and optional functions. The required functions are : All other functions are optional, but must be supplied to enable a certain functionality. For example, if the background shader has any parameters, the function must be supplied. It is also advisable to implement a function, if the function uses information which can be calculated once and does not change during the course of a rendering. It is important to note, that the function is called at least once for each pixel, potentially thousands of times during a single rendering. The faster the function, the faster the rendering will be.
