MatCaps support for light shading

[micheus]

Using a suggestion from a user on Discord (in April), I’ve been working since last month on changes to include the MatCaps light shader. I just finished it and have already applied it to the main repository.

There are dozens of MatCaps available out there, and they’re a great resource that lets us add different lighting styles to our workspace.

It was moved some View options to the submenu Show to open room to the new way to choose the light shaders. They are options we usually don't touch them frequently:


The new light shader options are now a selectable option (before was a combination of check and toggle):


The new MatCap option added to the View Settings:



Here is an updated screenshot of the View Settings window after I had added the option to blend the matcap shader with the diffuse/albedo texture map (normal map is enabled all the time):


and here the options in action:
