-/*
- * GL_ARB_vertex_shader test application. Feeds a vertex shader with attributes that
- * that have magic values and check if the values received by the shader are the same.
- *
- * Requires specific support on the GL implementation side. A special function printMESA()
- * must be supported in the language that prints variable's current value of generic type
- * to the appropriate shader's info log, and optionally to the screen.
- *
- * Perfectly valid behaviour produces output that does not have a line
- * beginning with three stars (***).
