The following test case draws different colors of text on a TYPE_BYTE_GRAY
buffered image. While the color of the normal text is the appropriate
gray value that is indicated at the top, the color of the antialiased text
is a fixed color. Examination of the source shows that the color for the
antialiased text is determined from an uninitialized variable.
