Also fixed Canvas MSAA (resolves issue #1271).
stencil-formatted Canvases can’t be drawn, and can only be used as the value for a new ‘depthstencil’ field to the table-argument variant of love.graphics.setCanvas.

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.

- Add love.graphics.newArrayImage, newCubeImage, and newVolumeImage.
- Add love.graphics.newCanvas(w, h, layers) and newCanvas(w, h, layers, settings). Add ‘type’ field to the settings table of newCanvas.
- Add new love.graphics.setCanvas variants: setCanvas(canvas, slice), and setCanvas(canvastable) where canvastable is in the format: {{canvas1, layer=2}, {canvas2, face=5}}
- Add Texture:getTextureType, getDepth, getLayerCount, getMipmapCount, and getFormat.
- Remove Image:getData and Image:refresh.
- Add Image:replacePixels(imagedata [, slice] [, mipmap]).
- Update Canvas:newImageData to accept a slice argument.
- Add love.image.newCubeFaces(imagedata).

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.

Each sprite in a SpriteBatch has 4 vertices in the following order: top-left, bottom-left, top-right, bottom-right. The index returned by SpriteBatch:add (and used by SpriteBatch:set) can be multiplied by 4 to determine the first vertex in a specific sprite.
Added new love.graphics.newMesh variants: newMesh(vertexformat, vertices [, drawmode, meshusage]) and newMesh(vertexformat, numvertices [, drawmode, meshusage]).
Replaced the regular love.graphics.newMesh variants with newMesh(vertices [, drawmode, meshusage]) and newMesh(numvertices [, drawmode, meshusage]). To use an image or canvas with a mesh, use Mesh:setTexture.
vertexformat is a table with the following prototype:
{
{attributename, datatype, components},
{attributename, datatype, components},
...
}
Where attributename is the name of the vertex attribute (can be the built-in names 'VertexPosition', 'VertexTexCoord', or 'VertexColor', or a custom name for use in a vertex shader), datatype is the type of values used for the attribute ('float' or 'byte'), and components is the number of components in the vertex attribute (between 1 and 4.)
The vertex format is used to determine the layout of the vertices in the mesh, for example the 'regular' newMesh variants use this vertex format:
format = {
{"VertexPosition", "float", 2},
{"VertexTexCoord", "float", 2},
{"VertexColor", "byte", 4},
}
The mesh usage parameter accepts the same constants as the spritebatch usage hint in love.graphics.newSpriteBatch - "dynamic", "static", and "stream".
Mesh:setVertex now sets *all* vertex attributes for a specific vertex in the Mesh.
Added Mesh:setVertexAttribute(vertexindex, attributeindex, attributevalue1, ...), which sets the values for a specific vertex attribute in a specific vertex in the Mesh (resolves issue #784.)
Added Mesh:getVertexFormat and Mesh:flush.
Added Mesh:setAttributeEnabled(attributename, enable) and Mesh:isAttributeEnabled(attributename), to enable or disable the use of a specific attribute when drawing the Mesh.
Added Mesh:attachAttribute(attributename, mesh), which makes the Mesh use a vertex attribute from another mesh when drawing the Mesh. This can be used to separate out vertex attributes which are updated at different rates into different meshes, and to share vertex data between multiple meshes.
Removed Mesh:setVertices, Mesh:getVertices, and Mesh:setVertexColors.
This will simplify the code and make it more maintainable when OpenGL ES 2+ support is added, compared to using the deprecated VA functions on desktop GL and the generic VA functions on GLES.
