…wport_outer_pos, viewport_inner_size, viewport_outer_size are stored as inner_pos, outer_pos, inner_size, outer_pos and Now every (i32, i32) is stored as egui::Pos2

Addes some documentation

* Refactor eframe wgpu

…ave his parent icon

…iewport

* Improve viewports example

Removed the last fix because there is not need for it now!

The crash was causated because sync viewport, when was cleaning up inactive viewports, was cleaning his parent before he got cleaned, and his parent when tring to resume was causing the crash

* Better performance because now the cleanup will be only run by the async viewports

…rect

* InputState::{outer_pos, outer_size} compacted to InputState::outer_rect
* RawInput::{inner_pos, inner_size} compected to RawInput::inner_rect
* RawInput::{outer_pos, outer_size} compected to RawInput::outer_rect
* Context::{viewport_inner_pos, viewport_inner_size} compacted to Context::inner_rect
* Context::{viewport_outer_pos, viewport_outer_size} compected to Context::outer_rect

…herit the icon of his parent

And refactoring and adding some inline documentation

…x_texture_side, and now on any egui_winit has max_texture_side set

…glow

The problem is that when we call Context::create_viewport_sync can be on any thread because egui::Context is Sync + Send but the backend is not!
So we want the callback to the backend to be thread local!

The problem that this adds is that now you cannot create more then one egui::Context,
 because the thread local variabile is static and i don't know how to store a non static LocalKey on egui::ContextImpl

…_viewports

I added drag and drop on every viewport, to make possible in the future to drag and drop between viewports

Fix Windows not rendering a sync viewport in a sync viewport

* fix typo
* fix == instead of !=
* added a spinner, to see if the redraw request are working as supposed to!

* now every viewport has his own frame_nr

eframe:
* some refactoring
* now on Windows spinner will make the async viewport refresh, this problem was only for async viewport in Windows

* problem found there are two redraw systems, one was broken now is fixed, the one that was broken on Linux X11 was not needed, but for Windows both are needed!
1: The egui repaint_callback system
2: The egui repaint_after from FullOutput

egui:
* removed FullOutput::repaint_after
* now for redraw only request_repaint_callback is used!
* now on every Context::request_repaint() will repaint only once
* exposed Context::requested_repaint and Context::requested_repaint_last_frame

eframe:
* now event result is returned as EventResult insted of Vec<EventResult>
* fix to many redraw requests

----:
* fix egui not waking when a repaint was from other thread
* now every thing feels more responsive!

* Fix web
* Fix errors from ./scripts/check.sh

…e, set_outer_position, set_inner_position and is making resizing smooter

* Fix msaa and depth textures for multiples viewports
* Fix panic when the width or height was 0

Added zoom shortcuts for viewports example

Fix ./scripts/check.sh errors

Better names
