Note that premultiplied alpha blending must be used with DXT1 alpha cutout textures if linear filtering is used, otherwise transparent black pixels will be blended with opaque non-black pixels resulting in dark fringes.
The Nvidia Tegra 3 driver for Android (used by Ouya) erroneously claims
to support the desktop-oriented GL_EXT_texture_array extension. On
desktop GPUs using (non ES) OpenGL, the glTexImage3D and similar
functions are always present, and the GL_EXT_texture_array extension
simply adds support for texture arrays to those functions. On OpenGL ES
2.0, those functions do not exist, and GL_OES_texture_3D is required to
define them.
Calling glTexImage3D on the Tegra 3 causes a segfault. This change works
around the issue by manually setting GLAD_EXT_texture_array to 0 on
OpenGL ES 2.0 systems, which causes LÖVE to avoid codepaths that assume
that the 3D texture functions are available. It doesn't make sense for
any OpenGL ES 2.0 GPU to claim support for GL_EXT_texture_array.
Fixes#1647
- 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.

- Added an optional mipmap index argument to the non-table variant of love.graphics.setCanvas, and an optional ‘mipmap’ field to the table variant.
- Canvas:setMipmapFilter now works.
- Added Canvas:generateMipmaps.
- Added Canvas:getMipmapMode.
- Added a new ‘mipmaps’ enum field to the table passed into love.graphics.newCanvas. Accepted values are “none” (default), “manual”, and “auto”.
If a Canvas has the manual mipmap mode, you will either need to render to a mipmap level or call Canvas:generateMipmaps. If it has the auto mode, mipmaps will be automatically generated after rendering to that Canvas. Generating mipmaps is not free.

- Add Texture:setDepthSampleMode(comparemode). Only works on textures with depth pixel formats. A texture with the depth sample mode set will only work with a depth sampler.
- Add DepthImage, DepthArrayImage, and DepthCubeImage sampler keywords to glsl3.

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.

effect() takes no arguments and returns nothing, you are responsible for assigning a value to either love_PixelColor or love_Canvases[n] in the function. You can declare ‘MainTex’, which will be whatever texture is used with any Drawable drawn with love.graphics.draw. You can also declare ‘VaryingColor’ and ‘VaryingTexCoord’, which are passed down from the vertex shader by love automatically. love_PixelCoord is also available.

- 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).

Add “instancing” Graphics Feature constant.
Add love.graphics.drawInstanced(mesh, instancecount, x, y, …) which draws the mesh multiple times in a single draw call. Each instance of the mesh will appear in the exact same spot unless one of the following are used:
- Add an optional vertex attribute step type argument to Mesh:attachAttribute. “pervertex” is the default. “perinstance” causes the attribute to be per-instance instead of per-vertex, when the mesh is drawn.
- Add love_InstanceID as a built-in read only int variable in GLSL 3 vertex shaders. It is always 0 except when a Mesh is drawn with more than 1 instance specified in the draw call. It can be used to manually compute or index into per-instance values in a shader.
