* add TODOs

* separate CosmicEdit from display

breaks loads of stuff: sizing, click functions, cursor hovering just a few

Only tested on login example

not optimized; spams handle weak clones to ensure got correct handle (will be fixed by new handle swapping routine)

not sure about the API changes but might just need to get used to it, is much more extensible

* break render function apart

centered padding now broken, not tested other text positions

* reshape earlier in render to fix padding issue

* move image creation to own system

* resize internal sprite to computed UI size

* prevent panic on zero size UI elements

* clicks + editor-display one-to-many relationships

* add render systemset

* fix hoverable invisible sprites

* update examples

* fix auto-height bugs

* clippy

adds a `CosmicCanvas` component to hold the image cosmic draws to. allows easier interop between UI and Sprite widgets

Each type of widget now uses a single `CosmicEditBundle`, adding widget specific components with `.insert()` or as tuples.

* first draft

* refine placeholder logic

bug: inputting and deleting a char on a widget quickly (i think at cursor blink speed) hold the input visually for that blink duration.

needs testing: placeholder specific attrs

* fix conflict with #73

* update placeholder attrs

* small fixes

* fix cursor showing on empty readonly widgets

should allow a user to install and use the plugin without needing their own install of cosmic-text

the violet color changed slightly when i set all the colors to bevy colors >.<

make edit history private; need less re-exports if this is just automagically added

removes CosmicEditor::set_text in favor of a set_text CosmicText component
