When enable DEBUG_BUILD, gd compile failed with error:
| ../../git/src/gd_tiff.c:961:64: error: 'image_type' may be used uninitialized in this function [-Werror=maybe-uninitialized]
| (image_type == GD_PALETTE || image_type == GD_INDEXED || image_type == GD_GRAY)) {
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~
actually, this warning is misinformation, we can see the logic from:
https://github.com/libgd/libgd/blob/master/src/gd_tiff.c
image_type will be assigned no matter force_rgba is TRUE/FALSE.
