Hi all,

I understand the example shown doesn't work if graphics state save/resotre
operation (q/Q operator) is inserted arount the text block.

However, reverting the change I made before (adding q-Q-bracket around
text) makes the fake-bold bug reappear.

Thus, I considered alternatives for fixing the fake-bold bug, however and
unfortunately, as this fake-bold feature relies on changing text rendering
mode (fill-then-stroke with adjusted stroke line-width) via "Tr" operator,
any fixes might be inherently incompatible with what Alexander wants to
(The possible fix here is to forcibly add "Tr" operator whenever new text
starts or font is changed)

Just my personal opinion but as I don't like this fake-bold feature although
it was added by myself, I rather want to make this feature obsolete...
