Change default projection in the render script

[britzl]

The default stretch projection is rarely the best choice. We should change this for new projects.

To not break old games one idea would be to update the template projects to use a new .render file.

Perhaps add

• stretch.render_script
• fixed.render_script
• fixed_fit.render_script
• perspective.render_script / 3d.render_script (or simply render both 2d and 3d, see below)

Other things to consider:

• Letterboxing
• Screen to world
• Render meshes and models

My separate proposition If you planing to update template projects in near future
#5592

I like the idea of having separate render scripts depending on the feature. That creates an easier entry point for newcomer and an introduction to the render scripts itself.
I guess of the other things to consider is the screen to world conversion. That is always something people bang their head on at first.
I was planning to do a video tutorial on this but I'll wait till the new features are implemented.
