    Fix bugs with alpha maps
    
    The alpha channel from the alpha map must be inserted as the new alpha
    channel when a scanline is fetched from an image. Previously the alpha
    map would overwrite the buffer instead. This wasn't caught be the
    alpha map test because it would only verify that the resulting alpha
    channel was correct, and not pay attention to incorrect color
    channels.

    Make mmx code compatible with Solaris Studio 12.3 compilers
    
    Rearranged some of the existing gcc & Intel compiler checks to allow
    easier sharing of common cases among the compilers.

    Reject trapezoids where top (botttom) is above (below) the edges
    
    When a trapezoid has a top/bottom that is above/below the left/right
    edges, degenerate trapezoids become possible. For example the edge
    could be very short and close to horizontal. If the bottom edge is far
    below the bottom point of such a short edge, the result is that the
    lower right corner of the trapezoid will be extremely far to the left.
    
    This kind of trapezoid causes overflows in the rasterization code, so
    change pixman_trapezoid_valid() to reject them.

    Fix some signed overflow bugs
    
    In the macros for the PDF blend modes, two comp1_t variables are
    multiplied together and then used as if the result were a
    comp4_t. When comp1_t is a uint8_t, this is fine because they are
    promoted to int, and the product of two uint8_ts fits in an
    int. However, when comp1_t is uint16, the product does not necessarily
    fit in an int, so casts are necessary.
    
    Fix for bug 43906, reported by Siarhei Siamashka.

    pixman-image.c: Fix typo in pixman_image_set_transform()
    
    A parenthesis was misplaced so that the size argument to memcmp() was
    always 0. The bug is harmless except that the flags might be
    unnecessarily recomputed in some cases.
    
    A bug reporting this in Mozilla's fork was discovered here:

    gradient-walker: For NONE repeats, when x < 0 or x > 1, set both colors to 0
    
    ec7c9c2b6865b48b8bd14e4 introduced a bug where NONE gradients would be
    misrendered, causing the area outside the gradient to be treated as a
    (very) long fade to transparent.The problem was that a check for
    positions outside the gradients were dropped in favor of relying on
    the sentinels.
    
    Aside from misrendering, this also caused a signed integer overflow
    when the code would compute a stepper size based on MIN_INT32.
    
    This patches fixes the issue by reinstating a check for these cases
    and setting both the right and left colors to transparent black.

    Android Runtime Detection Support For ARM NEON
    
    This patch adds runtime detection support for the ARM NEON fast paths
    for code compiled with the Android NDK. This is the only code change
    needed to enable the ARM NEON pixman fast paths for the ever growing
    Android platform (200 million+ smartphones, tablets, etc.). Just make
    sure to #define USE_ARM_NEON in your makefile.

    test "$test_CFLAGS" == "" &&         \
    
    may cause an error on some POSIX shells and uses a style which is not
