* Typically the inner loop here works on Argb input data, an
* Argb color, and produces ArgbPre output data. To use that
* standard approach we would need a FourByteAbgrPre to IntArgb
* 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.
