/**
* \name ActiveShaderProgram-invalid-program.c
* Verify glActiveShaderProgram with invalid program parameter
*
* There are several cases outlined in the GL 4.4 spec where
* glActiveShaderProgram should generate specific errors. In addition,
* section 2.3.1 (Errors) says:
*
* "Currently, when an error flag is set, results of GL operation are
* undefined only if an OUT_OF_MEMORY error has occurred. In other cases,
* there are no side effects unless otherwise noted; the command which
* generates the error is ignored so that it has no effect on GL state or
* framebuffer contents."
*
* After calling glActiveShaderProgram with an invalid parameter, verify that
* the active program state has not been modified.
