Alex Szpakowski 70b32c47ce Error if a non-2D/affine matrix is used with auto-batched draws, since they perform CPU-side matrix transforms on 2-component vectors.

Alex Szpakowski 7161d600b7 Add mipmapping support to Canvases.
- 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.

Alex Szpakowski a0ef2ac28b Add Depth compare / shadow sampler support. Officially this is only supported in glsl3 shaders.
- 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.

Alex Szpakowski 0001b4695e Add new variants of love.graphics.clear for controlling how the depth and stencil buffers are cleared.
- 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.

Alex Szpakowski 018a3831cb Add a new “stencil8” pixel format for Canvases (resolves issue #1003).
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.

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 ff8358a979 Removed void effects(…) pixel shader prototype. Added void effect(). Allows calling love.graphics.draw with textures of different types with a custom shader without having an extra sampler2D.
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.

Alex Szpakowski 73fd45558b Implement Array, Cubemap, and Volume texture types (issue #1111).
- 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).

Alex Szpakowski bea7cfdaab Add low-level hardware instancing support to Meshes.
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.

Alex Szpakowski 731b5d5cf0 Added support for GLSL 3 shaders (GLSL 3.30 and GLSL ES 3.00).
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.
