/**
 * Test that invalid transparent colors can't be read
 *
 * We're reading a corrupt palette image in GD2 format, which has only a single
 * palette entry, but claims that the transparent color would be 1.  We check
 * that the transparency is simply ignored in this case.
 *
 * See also <https://github.com/libgd/libgd/issues/383>
