Alex Szpakowski 9fe81ad922 Allow a temporary/internal depth buffer to be used when a Canvas is active, similar to how temporary stencil buffers are allowed.
Syntax is setCanvas{canvas [, depth=true, stencil=true]} or setCanvas{canvas, depthstencil=true}.

Alex Szpakowski ac697ddb0f Clean up love’s internal Vector code a bit, and rename it to Vector2 so it’s more obvious what it is.

Alex Szpakowski 621fb24ba1 Require stencil=true to be specified in setCanvas if stenciling is used while a Canvas is active and there is no custom stencil buffer.

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 43172bd3f6 Add optional ‘readable’ boolean field to the table passed into love.graphics.newCanvas. Added new variant of love.graphics.getCanvasFormats which takes a ‘readable’ boolean.

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 08a377ff30 Rename love.graphics.flush to love.graphics.flushBatch.
Mesh/Spritebatch/Text:flush already exist and do something a bit different (flush vertices instead of render a pending batch).

Bart van Strien b205b8a020 Remove references to old LOVE_ENABLE_module_implementation defines
As far as I know they are no longer used, as autotools was the primary (only)
user and it now switches entire modules.
I've also taken the opportunity to clean up the default list in
src/common/config.h.
Oh yeah, and this fixes linux builds not having graphics or audio backends.

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 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).
