The ODG test file

I'm using this build: https://git.libreoffice.org/core/+log/d56cc158d8a96260b836f100ef4b4ef25d6f1a01

The exports of PNG and WEBP have some bugs. To reproduce:

1. Open bug-example.odg in Draw
2. Export -> PNG -> Do not include transparency
3. Notice image appears normal -> see png-without-transparency.png
4. Export -> PNG -> Include transparency
5. [BUG] Notice text in image is missing color -> see png-with-transparency.png
6. Export -> WEBP
7. [BUG] Notice there is no option for "Include transparency"
8. Notice image appears normal -> see webp-without-transparency.webp
