If a shader uses gl_PointSize then it can only be used when drawing points. If a shader doesn't use gl_PointSize then it can't be used when drawing points.
Added 'ConstantPointSize' and 'CurrentDPIScale' built-in shader uniforms.
ConstantPointSize is in DPI-scaled points, whereas gl_PointSize is in pixels, so to get the correct default behaviour a shader needs to do gl_PointSize = ConstantPointSize * CurrentDPIScale
Allows buffers created with love.graphics.newBuffer to only allocate VRAM data. Previously they had a copy of their contents in RAM.
Also makes it easier to implement Buffers in other graphics APIs and to implement more types of Buffers in the future.
- 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.

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>...

I opted to remove the optional parameters altogether since they seemed oddly
out-of-place. They used to reset the values to defaults when not supplied, and
they also weren't returned by getAreaSpread(), so
setAreaSpread(getAreaSpread()) actually changed spread parameters.
The other option was to remove the separate getters/setters for
AreaSpreadIsRelativeDirection and AreaSpreadAngle, and fully rely on
setAreaSpread for these parameters, but the rest of the ParticleSystem API
tends to keep parameters separate.

2 new Particle System Distribution types:
borderellipse - spawns new particles around the border of an elllipse shape defined by dx,dy
borderrectangle - spawns new particles around the border of a rectangle shape defined by dx, dy
New functions:
getAreaSpreadAngle()
getAreaSpreadIsRelativeDirection()
setAreaSpreadAngle(angle in radians)
setAreaSpreadIsRelativeDirection(boolean)
setAreaSpread(distribution, x, y, (optional)angle, (optional)isRelativeDirection)
- angle - defaults 0. In radians the angle to rotate the entire area spread distribution
- isRelativeDirection - defaults false. When false, particles will travel in the direction defined by setDirection(). When true, particles will travel away from the center of the area spread shape

branch : particle system new features
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.
