/*
* Unit tests for Bug464
* Some ATI-Drivers crash the JVM if VBO-related glFunctions are called. This test checks
* if TextRenderer calls any of these functions while it's useVertexArray variable is set
* to false.
* 2D- and 3D-TextRendering is tested by creating a GLCanvas showing a simple line of text
* while filtering all glFunction calls by using a modified version of TraceGL2.
* VBO-related function are logged to the disallowedMethodCalls String of the GLEventListener
* instead of being executed (to prevent JVM crashes). Therefore, if the
* disallowedMethodCalls isn't an empty String after the test, the test fails.
*
* Other classes related to this test:
* TestTextRendererGLEventListener01
* TestTextRendererTraceGL2Mock01
