| * converter for the front end and an IntArgbPre to FourByteAbgrPre |
| * converter for the back end. The converter exists for the |
| * front end, but it is a workaround implementation that uses a 2 |
| * stage conversion and an intermediate buffer that is allocated |
| * on every call. The converter for the back end doesn't really |
| * exist, but we could reuse the IntArgb to FourByteAbgr converter |
| * to do the same work - at the cost of swapping the components as |
| * we copy the data back. All of this is more work than we really |
| * need so we use an alternate procedure: |
| * - Copy the data into an int-aligned temporary buffer (if needed) |
| * - Convert the data from FourByteAbgrPre to IntAbgr by using the |
| * IntArgbPre to IntArgb converter in the int-aligned buffer. |
| * - Swap the color data to Abgr so that the inner loop goes from |
| * IntAbgr data to IntAbgrPre data |
| * - Simply copy the IntAbgrPre data back into place. |
