👑 REPLY FIELDS 👑

• response_type — the type of this reply, in this case XCB_RANDR_GET_SCREEN_INFO. this field is also present in the xcb_generic_reply_t and can be used to tell replies apart from each other. it's giving "hello, it's me" energy 💅
• sequence — the sequence number of the last request processed by the X11 server.
• length — the length of the reply, in words (a word is 4 bytes).
• rotations — TODO: NOT YET DOCUMENTED.
• root — TODO: NOT YET DOCUMENTED.
• timestamp — TODO: NOT YET DOCUMENTED.
• config_timestamp — TODO: NOT YET DOCUMENTED.
• nSizes — TODO: NOT YET DOCUMENTED.
• sizeID — TODO: NOT YET DOCUMENTED.
• rotation — TODO: NOT YET DOCUMENTED.
• rate — TODO: NOT YET DOCUMENTED.
• nInfo — TODO: NOT YET DOCUMENTED.

not me listing a whole pile of TODOs 😭 that's genuinely what the original page has though, so we keep every single one. the vibe changes, the facts do NOT. periodt.
