Add sync and async texture and buffer readback APIs.
...
- Add imagedata = love.graphics.readbackTexture(texture, [slice, mipmap, x, y, w, h, [dest, destx, desty]]).
- Add readback = love.graphics.readbackTextureAsync(texture, [slice, mipmap, x, y, w, h, [dest, destx, desty]]).
- Add bytedata = love.graphics.readbackBuffer(buffer, [offset, size, [dest, destoffset]]).
- Add readback = ove.graphics.readbackBufferAsync(buffer, [offset, size, [dest, destoffset]]).
- Deprecate Texture:newImageData.
The async variants return a new GraphicsReadback object. It has the following methods:
- isComplete()
- hasError()
- wait()
- getBufferData()
- getImageData()
- update() (called automatically every frame by love, not normally needed).
Support notes:
- readbackBuffer and readbackBufferAsync require buffer copying support.
- readbackTexture with a render target (canvas) is always supported. readbackTexture with a non-render-target requires copy-texture-to-buffer support.
- readbackTextureAsync with a render target requires copy-render-target-to-buffer support. readbackTextureAsync with a non-render-target requires copy-texture-to-buffer support.

Add love.graphics.setStencilMode. Remove old stencil API.
...
- Add setStencilMode(drawaction, comparemode, value = 0, readmask = 0xFF, writemask = 0xFF).
- Add getStencilMode.
- Remove love.graphics.stencil.
- Remove love.graphics.set/getStencilTest.
Note that the new setStencilMode API does not clear the stencil buffer, and does not turn off color writes (it can still be done manually), unlike love.graphics.stencil.
Fixes #1161 .
Fixes #1251 .

Refactor Buffer internals.
...
Allows buffers created with love.graphics.newBuffer to only allocate VRAM data. Previously they had a copy of their contents in RAM.
Also makes it easier to implement Buffers in other graphics APIs and to implement more types of Buffers in the future.

Handle backbuffer MSAA manually in love.graphics code

Previously love would use SDL APIs to make the system (WGL etc) handle it, which meant the OpenGL context had to be recreated whenever MSAA changed.

Add new texel buffer type.
...
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).
