      I am creating a volatile image out of default graphics configuration and getting the ImageCapabilities object from the volatile image. isTrueVolatile() method of this ImgCapabilities object returns true. I am getting the image capabilities object from the graphics config directly and calling isTrueVolatile(). This object returns false which is incorrect. Actually the image is truely volatile in the sense that it can lose it's surfaces and hence the graphics config must also return true for isTrueVolatile().

      This is noticed on WinXP with OpenGL turned on, right from Tiger-beta2-b46. This is not reproducible with DDRAW/NODDRAW.

      I have attached a testcase which would print the outout of isTrueVolatile() to the console. Execute it with OpenGL flag turned on. If the default config returns false, the bug is reproduced.

      I am using a NVIDIA GEFORCE4 MX440 video card.
