Graph Edit - mouse wheel should zoom by default and not scroll

[EricEzaM]

Godot version:
3.2.2 and 4.0

OS/device including version:
Any

Issue description:
I think the graph edit should zoom by default rather than scroll up and down, like Blenders compositing view. It feels a lot more natural imo. Also current there is no mouse wheel shortcut to zoom... which feels really bad. I usually like navigating in node-based workflows (like UE4 bluprints) by zooming in and out. Only having the on-screen buttons to do this feels clunky.

The code is there to do this... I have no idea why it was commented out. Enabling it makes it work perfectly fine. This comment was made by reduz in 34c022a over 4 and a half years ago. I think it works fine, however it could feel better once combined with adjustments made possible by PR #38261.

Lines 1010 to 1018 in a609b30

	if (b->get_button_index() == BUTTON_WHEEL_UP && b->is_pressed()) {
	//too difficult to get right
	//set_zoom(zoom*ZOOM_SCALE);
	}
	if (b->get_button_index() == BUTTON_WHEEL_DOWN && b->is_pressed()) {
	//too difficult to get right
	//set_zoom(zoom/ZOOM_SCALE);
	}

Also I have tested it using set_zoom_custom(<zoom>, b->get_position()) so it zooms to your mouse position, and it feels really good.

The original reason was that zooming makes scaling 2d look bad, but antialiasing is off in master so it doesn't show.

That was the original reason for the disable.

Duplicate of #5214, however since it targets only Visual Shader I will close the old one

Closing in favor of godotengine/godot-proposals#2352, as feature proposals are now tracked on the Godot proposals repository.
