Alex Szpakowski 3435a6bcbf Change the internal constant color from a (per-draw) vertex attribute to a uniform. Pack most built-in uniforms into a single vec4 array and update them all with a single glUniform call.

Michael Vetter a1d6da4624 Silence compiler warning
Silence compiler warnings about methods with return value and potentially not returning anything.
This happens with gcc8 and the `-O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector-strong -funwind-tables -fasynchronous-unwind-tables -fstack-clash-protection -std=c++11` flags passed to it by default on openSUSE.

Alex Szpakowski 7354de2059 Add (low level) functionality to allow rendering 3D Meshes.
- Add love.graphics.setDepthMode(testcomparison, enablewrites).
- Add love.graphics.setMeshCullMode.
- Add love.graphics.setFrontFaceWinding.

Depth testing and depth writes require a depth buffer to work. The mesh cull mode controls whether front/back faces of a mesh are culled. The front face winding determines whether a clockwise or counterclockwise-oriented face in a mesh is considered front facing.

Bart van Strien 9e4374935d Show (short) list of possible enum values when an invalid value is encountered (resolves #1318)
All enum errors have (hopefully) been changed to a luax_enumerror, which has a
fixed error message. If additionally a list of valid options is passed, it
lists that in the error message. For every enum error with few options I've
implemented this using a getConstants call.

This solution has been designed specifically to reduce the number of template
instantiations (as I've been told that was a concern). All new template code
happens in places where there already was an instantiation of the relevant
StringMap. Of course there is still std::vector<std::string>...

Alex Szpakowski 66b299822a Array textures can be easily drawn without a shader (resolves issue #1111).
Added love.graphics.drawLayer(texture, layerindex, …). ‘texture’ must be an array texture.
Added SpriteBatch:add/setLayer.

Added Quad:get/setLayer. This applies to array textures that are drawn without specifying an explicit layer index in the draw call.

Added love.graphics.newQuad variants which have layer arguments.

Alex Szpakowski 0d2e08baff Implement automatic batching for points, lines, shapes, and images/quads.
The above are batched together into a single draw call when called without other drawing calls in between, as long as the following criteria are met:

- The texture is the same.
- The primitive type is the same (points cannot be batched with non-points).
- The love.graphics state is the same (aside from the current color - i.e. setColor - and the transform state).
- The active shader’s uniform values are the same.

You can examine the ‘drawcalls’ field of love.graphics.getStats() to help determine if your code is allowing for optimum batching.
