* FUNCTIONS: fglEnablePerFragUnit
* SYNOPSIS: This function enables and disables various per-fragment capabilities:
* scissor test, alpha test, stencil test, depth test, blending
* and logical operation.
* PARAMETERS: [IN] unit: a enum value indicating an per-fragment capability.
* [IN] enable: a boolean value to enable or disable.
* RETURNS: FGL_ERR_NO_ERROR - if successful.
* FGL_ERR_INVALID_PARAMETER - unit was not one of the values listed
* in the FGL_PerFragUnit
* ERRNO: FGL_ERR_NO_ERROR 1
* FGL_ERR_INVALID_PARAMETER 3
