https://pdfium-review.googlesource.com/c/pdfium/+/136570 has landed an implementation of `EncodeBGRAPNG` that ignores `discard_transparency`. This behavior was different from the old, `libpng`-based implementation as shown by the new `EncodeBGRAPNGAndDiscardTransparency` test where the last assertion (`EXPECT_EQ(rgba_output[3], 255)`) would pass with `libpng`-based implementation but (before this CL) fail with the Rust-based implementation.
