Without this, we get "subscripted value is neither array nor pointer"
error from the compiler.
Since this is a build fix for powerpc platforms, no PKGREVISION bump.
A new pixman release 0.34.0 is now available. This is a major release,
following three development releases in the past six months. It contains
all the changes detailed in the last three development releases in the 0.33
series.
For those who didn't follow the development release announcements, the 0.34
version contains major improvements to ARMv6 and POWER (both BE and LE)
architectures, enhancements of tests and utilities and important bug fixes.

commit eb53d111bd8651cd00c1b728b09e8be09b8482f7
Add a lossy 32-bit generic pixel fetch function for wide surfaces.
The transformed fetch path currently only works at 32-bit precision.
Until a wide version of that function is added, we need to have a
path to perform a wide FetchPixel and then contract it down to
a8r8g8b8.
Also, use the right format when expanding the result in
fbFetchTransformed64. fbFetchTransformed returns a8r8g8b8 results.

Take the source format into account in pixman_expand.
Extract the original bits of the source image for each
component and then replicate up to 16 bits to fill the wide
components. Make sure to hard-code the alpha value to 1 if
the source format didn't have alpha.
commit c0d98e96605c6d03f4b02f337f2f5827165bb092
Make expansion and contraction loops clearer.
commit fc0b28bf6af81428b7ac045614eea97fbf9c4a70
Add wide source picture, external alpha, and transformed
image routines. The wide external alpha path should work
correctly with wide formats. The wide transformed fetch code for
now just does a 32-bit fetch and then expands, which will lose
precision. Source pictures, for now, are evaluated at depth 32
and then are expanded to depth 64. We could get higher precision
by evaluating them directly at depth 64, but this should be good
enough for now.
commit 42a3a2d6fc8d3e521c6914ff8fb89f1fbc673e28
Add wide fetch/store functions.
Use the narrow ones and expand/contract where necessary. Still
need wide paths for fancy pictures, but this gets the
basic stuff working.
commit 7591d3f1d7e0884f9362018edf720724095cf380
Add expand and contract functions to convert between ARGB8
and ARGB16. The expansion function isn't quite correct,
but gives reasonable results.
