`GL_LINES` isn't suitable, because it makes lines between pairs of 2 vertices,
not loops around 3 vertices.
Support for OpenGL ES isn't simple, as it has no `glPolygonMode`. And showing broken
wireframe (i.e. with `GL_LINES`) would cause confusion.
- The editor is accessible via the pause menu and the settings menu.
- Buttons can be moved via drag & drop.
- Buttons can be added/removed. The grid menu added by #14918 is used to show
all buttons not included in the layout.
- Custom layouts are responsive and adapt to changed screen size / DPI /
hud_scaling.
- The layout is saved as JSON in the "touch_layout" setting.
Easy way to reproduce:
1. Connect a bluetooth mouse to your Android phone with Minetest installed
2. Play Minetest
3. Slowly move the mouse to the right so that the camera rotates continously
4. While still moving the mouse continously, tap the screen a few times per second
Before this commit: The camera jumps around randomly.
After this commit: The camera moves like it should.
This is a combination of two Irrlicht changes copied from MoNTE48/irrlicht
and one Minetest change authored by me. I have no idea why this works, but
it does work and I have spent way too much time on this bug already.
This PR adds a variety of effects to enhance the visual experience.
"soft" clouds look
Tinted shadows
Crude water reflections (sky and sun) and waves
Translucent foliage
Node specular highlights
Adjusted fog color (more saturated where the fog is lighter)
Minor changes to volumetric lighting (crudely simulates the effect of depth)
