Chromium currently builds against the OSX 10.5 SDK on both LEOPARD and SNOW LEOPARD, which causes BUILDING_ON_LEOPARD to be defined via <wtf/Platform.h>. Gradient.h defines #define USE_CG_SHADING defined(BUILDING_ON_TIGER) || defined(BUILDING_ON_LEOPARD) making the gradient paint path use the older CGShaders - CGShadingCreateRadial is used for radial gradients, but does not support ellipsoidal gradients (this bug). Using the newer CGContextDrawRadialGradient for radial gradients would fix the bug, but it would also cause memory leaks for linear gradients via CGContextDrawLinearGradient on 10.5 SDK builds of the Gradient.h code (refer to changeset 54970). Best to fix this once Chromium has real 10.6 SDK build/release system (USE_CG_SHADING will be false) and rebaseline the layout tests to close this bug.

Alternative fix, use skia on the mac, the skai implementation know how to draws ellipsoids as required by these tests.
