The following table describes the support level of various operations across API levels:
-In addition, some operations behave differently with hardware acceleration enabled:
- -XOR,
- Difference and ReverseDifference clip modes are ignored. 3D
- transforms do not apply to the clip rectangle| + | + | + | + | + |
