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
GLSL 3+ shaders can read from texel buffers by declaring a uniform samplerBuffer variable and calling texelFetch with a 0-based index, in the shader code. All attributes in a texel buffer's format array must have the same data format (e.g. all 'floatvec4' formats).
Shader:send accepts a texel Buffer for samplerBuffer uniforms.
Added 'texelbuffer' to love.graphics.getSupported (requires GLSL 3+ and desktop OpenGL).
Added 'texelbuffersize' to love.graphics.getSystemLimits. Returns the max number of values in a texel buffer (array length multiplied by the number of attributes declared in the buffer's format array).
Also changed the optional 'columnMajor' argument of the matrix variant of Shader:send and Transform:setMatrix to accept enum constants instead. Valid values are "row" and "column".

- 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.

- Add love.graphics.clear(r, g, b, a [, stencilvalue, depthvalue]).
- Add love.graphics.clear(color1, color2, …, [, stencilvalue, depthvalue]).
- Add love.graphics.clear(false, stencilvalue, depthvalue).
stencilvalue and depthvalue are either true, false, or a number. True is the default behaviour and clears that buffer to the default value (0 for stencil, 1 for depth), false prevents clearing.
The third variant listed above only clears the depth and/or stencil buffers and not the color buffer.

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).

To use GLSL 3 in a shader, the first line of the shader has to be: #pragma language glsl3
glsl1 is the default language.
Added “glsl3” graphics feature as part of the table returned by love.graphics.getSupported().
Added love.graphics.validateShader(boolean gles, shadercode). It returns a boolean along with an error string if the shader code has errors for its target language and platform (gles or desktop).
Implemented support for Core Profile OpenGL 3.3 in love.graphics.
