Does devg-extreme2 supports hardware stencil operations ? I chose framebuffer config, which has RGBA8888 format with 24 
bit depth size and 8 bit stencil size (ID: 6).

My application works on ATI OpenGL ES emulator, QNX's software OpenGL ES implementation, but doesn't work on devg-
extreme2. The symptoms are as follows: stencil states and operations are completely ignored, there are no stencil buffer
 fillings  occured during rendering to stencil buffer.
