+Repro steps:
+
+build, install and run the attached test program TestViewport.apk
+
+Run on Sapphire with Froyo.
+
+The program clears the screen to blue, then draws a full screen white quad that
+is alligned to the screen.
+(Therefore the whole screen should appear to be white.)
+
+
+Note that screen is all white.
+
+Rotate screen 90 degrees.
+
+Expected: screen is still all white.
+
+Actual: screen is blue with offset white rectangle.
+
+This bug only happens on Sapphire, it works correctly on Passion.
+
+What happens:
+
+I think the bug is that the gl.glViewport() call in onSurfaceChanged() is
+being ignored by the OpenGL driver.
+
+NOTE: If a gl.glViewport call is added at the beginning of the onDrawFrame()
+call (which means it is called before every draw), the program runs correctly.
