This supersedes the existing optional hinting and dpi scale parameters. The table's fields are:
{
hinting = "normal",
dpiscale = 1, -- nil will default to the current window DPI scale.
}
This a significant refactor / rewrite of much of the love.graphics Font code.
Text positioning is now split into TextShaper classes in the love.font module. This isn't exposed to users yet.
BMFonts and ImageFonts use the same text shaping as before (in the new TextShaper API). Fonts loaded via FreeType now use Harfbuzz for text shaping.
The new code isn't at feature-parity with the old code yet. Harfbuzz-based text shaping enables kerning support in more fonts, character combining into ligature glyphs, and directions other than left-to-right (this isn't supported in love yet).
It should be preferred instead of Data:getPointer because the latter uses lightuserdata which can't store more all possible memory addresses on some new arm64 architectures, when LuaJIT is used.
All enum errors have (hopefully) been changed to a luax_enumerror, which has a
fixed error message. If additionally a list of valid options is passed, it
lists that in the error message. For every enum error with few options I've
implemented this using a getConstants call.
This solution has been designed specifically to reduce the number of template
instantiations (as I've been told that was a concern). All new template code
happens in places where there already was an instantiation of the relevant
StringMap. Of course there is still std::vector<std::string>...

- Moved love.math.compress / decompress / decode / encode / hash to love.data.
- Changed love.data.compress/decompress to take the format argument first instead of second.
- Added love.data.newDataView. Returns a read-only subsection of an existing Data object.
- Added love.data.newByteData. Mostly useful in combination with LuaJIT's FFI as it has no extra methods currently.
- Added implementations of Lua 5.3's data packing APIs: love.data.packString / packData / unpack / getPackedSize.
Resolves issue #1336.

With the highdpi window flag enabled on a retina-capable display and OS, content should now appear to the user at the same size and in the same positions as with the flag disabled.
As a result, mouse and touch coordinates, Texture and graphics dimensions, and the graphics coordinate system now use pixel density-scaled units instead of pixels. Raw pixel units should generally only be used for things such as shader algorithms which execute per-pixel and rely on accurate pixel dimensions. love.window.fromPixels and friends typically don’t need to be used anymore.
Images, Canvases, and Fonts can have an optional explicit ‘pixel density’ set when creating them. This allows for easily loading high pixel density content which displays at the same size as regular or low pixel density content.
API changes:
- Added Texture:getPixelWidth/getPixelHeight/getPixelDimensions and Texture:getPixelDensity. Texture:getWidth/getHeight return the pixel density-scaled width and height (as it will appear on the screen when drawn) rather than the number of pixels on each texture dimension.
- Added love.graphics.getPixelWidth/getPixelHeight/getPixelDimensions.
- Added optional ‘pixeldensity’ field to the settings table parameter of love.graphics.newImage. It defaults to 1, or if the file the Image was loaded from has “@2x”, “@3x”, etc. at the end of its name, it uses that number as the pixel density scale by default.
- love.graphics.newCanvas now takes a table as its third parameter, with fields “format”, “msaa”, and “pixeldensity”. pixeldensity defaults to the main screen’s pixel density. The width and height parameters specify the visual size that the Canvas will be drawn at / can be drawn to (pixel density-scaled units).
- love.graphics.newVideo accepts a table as its second parameter, with optional fields “audio” and “pixeldensity”. pixeldensity defaults to 1.
- love.graphics.newFont variants have an optional pixeldensity parameter at the end of the argument list. For TrueType fonts this defaults to the current pixel density scale of the screen, and for BMFonts and ImageFonts this defaults to 1.
- Added Font:getPixelDensity.
- Renamed love.window.getPixelScale to love.window.getPixelDensity.

Instead of a global type enum and bitfield, all types now have their own
love::Type static member. This means they automatically assign their ids, build
their bitsets, etc. As a bonus, it simplifies wrapper code since most functions
already know which type they're pushing to or getting from lua, so they can
directly get the static member (if it's called 'type').

Since the type is passed to va_start, and apparently that's undefined behaviour if it's a reference.
<Textmode> the best kind of behavior
