Egui text agent feature

[buxx]

Hello,

I'm working about to find a way to integrate the egui text agent feature which permit to smartphone virtual keyboard to show up on egui text field. I started to study egui side mechanism.

Text agent is "installed" by https://github.com/emilk/egui/blob/713917e4819d9c26068aec286ee675f7e3bff907/egui_web/src/text_agent.rs#L24 which is called from egui::start : https://github.com/emilk/egui/blob/master/egui_web/src/backend.rs#L365

Can you give me some information about egui miniquad integration to permit me to add this text agent ?
