Margin needs to have a high enough value for test body motion to work
properly (separate using the margin, move without then gather rest info
with the margin again).
Fixes issues with test motion returning no collision in some cases with
margin equal to 0.
* Adds proxy support for `HTTPRequest`.
* Adds `network/http_proxy/{host,port}` editor settings.
* Labeled as "HTTP Proxy" and it will be used for both HTTP and
HTTPS requests. This is the same convention as seen in Android
Studio's proxy settings.
* Makes Asset Library and Export Template Manager use proxy according to
the editor settings.
Exposes a method in `EditorInterface` to open scripts on a specified
line and column. This method handles if the internal or the external
editor should be used.
GPUParticles attractors and collision are currently only available in 3D.
Their 2D counterparts haven't been implemented yet, but they will use
separate nodes.
Helps with discovery and setup of physics solver settings, in a specific
project settings section for both 2D and 3D.
Other changes for cleanup:
-Removed unused space parameters in 3D
SPACE_PARAM_BODY_ANGULAR_VELOCITY_DAMP_RATIO
SPACE_PARAM_CONSTRAINT_DEFAULT_BIAS
-Added custom solver bias for Shape3D (same as Shape2D)
-Improved documentation for solver settings
A summary of the tweaked descriptions:
* "get_camera_position()" is explains what the camera position is, and mitigates the confusion between this method and Node2D.position;
* "get_camera_screen_center()" links to the "get_camera_position" method;
* "reset_smoothing()" links to the "smoothing_enabled" propriety;
* "drag_horizontal_offset" and "drag_vertical_offset" link to their respective _enabled_ properties;
* "limit_smoothed" links to the "smoothing_enabled" propriety;
* "rotating" clarifies that the camera _view_ rotates when enabled.
Partially closes https://github.com/godotengine/godot-docs/issues/5417, as some of the issues described are no longer present in 4.0, or are not fully solved in this PR.
Further tweaks are welcome, as I'm afraid this could be a too verbose. A few of these could be split into their PR if necessary.
