/*
Unity editor script to precisely move, rotate and scale GameObjects on 2D scenes, using the arrow keys.

Notes:
- To use it just include it on an "Assets/Editor" folder on your project.
- The action depends on the selected tool and the size of the movement depends on the Scene view zoom.
- The more "zoomed in" is the scene view the smaller is the movement step. 
- It will work when the current Scene tab is in 2D mode and there is at least one gameObject selected,
otherwise the scene camera will move as usual :)

You should not use the Open SSH client that comes with Git for Windows. Instead, Windows 10 has its own implementation of Open SSH that is integrated with the system. To achieve this:

1. Start the ssh-agent from Windows Services:

• Type Services in the Start Menu or Win+R and then type services.msc to launch the Services window;
• Find the OpenSSH Authentication Agent in the list and double click on it;
• In the OpenSSH Authentication Agent Properties window that appears, choose Automatic from the Startup type: dropdown and click Start from Service status:. Make sure it now says Service status: Running.

2. Configure Git to use the Windows 10 implementation of OpenSSH by issuing the following command in Powershell:

git config --global core.sshCommand C:/Windows/System32/OpenSSH/ssh.exe

Computational Fluid Dynamics (in graphics mostly)

Disclaimer: I have no professional education in Compulational Fluid Dynamics, these are various notes on what I found/learned when trying to learn a bit on the topic. Some of the notes lack sources as I wrote them up later often just remembering some StackExchange answer. Some things I might have misinterpreted.

This note simply gathers some info and thoughts on building Node Editor, especially in an
immediate mode setting.

Q: How does imgui render rounded rects?
Check imgui AddRectFilled
Imgui drawing api is closer to nanoVG
 - Path is kept
 - Contents are modified based on path

> ¿Cómo cambio el tamaño de las fonts?

En DemoWindow > Configuration > Fonts :

• Para cambiar el tamaño de la font de una sola ventana, existe ImGui::SetWindowFontScale(window_scale), donde window_scale es un float que va desde 0.0 (tamaño casi invisible) a 2.0 (tamaño doble que el normal).
• Para cambiar el tamaño de una font en todas las ventanas, alcanza con modificar io.FontGlobalScale. io es el contexto de ImGui que se obtiene en la inicialización. FontGlobalScale es un float que va desde 0.0 (tamaño casi invisible) a 2.0 (tamaño doble que el normal).
