I would like to remind osx users that this change might cause build to
fail if HomeBrew (with libpng) or XQuartz is installed, unset PATH before
running ./configure so that libpng-config won't interfere.
A question about code around line 5919 of image.c,
Shouldn't this if conditional wrap the last line in?
/* We use the current frame background, ignoring any default
background color set by the image. */
#if defined (HAVE_X_WINDOWS) || defined (HAVE_NTGUI)
XColor color;
png_color_16 frame_background;
color.pixel = FRAME_BACKGROUND_PIXEL (f);
x_query_color (f, &color);
memset (&frame_background, 0, sizeof frame_background);
frame_background.red = color.red >> shift;
frame_background.green = color.green >> shift;
frame_background.blue = color.blue >> shift;
#endif /* HAVE_X_WINDOWS */
fn_png_set_background (png_ptr, &frame_background,
PNG_BACKGROUND_GAMMA_SCREEN, 0, 1.0);
