luaotfload/src, branch v2.6-rc3

[*] tidy up headers, attributions

2015-11-29T21:46:38+00:00

[main] refine very early logging

2015-11-29T21:35:33+00:00

This kludge dumps the input arguments on one line each -- fix this by
defining a dumb imitation of our real logger that is installed later on.

[conf] ensure correct fontloader is loaded without config file

2015-11-29T21:26:45+00:00

[loaders] customize define_font reset

2015-11-29T21:04:03+00:00

This function needn’t be as general for this kind of callback. The new
implementation is simpler but also complains about irregularities like
multiple registered functions.

[aux] fix typo in function name

2015-11-29T20:41:23+00:00

Doesn’t seem like anyone is using these since this would’ve exploded
immediately …

[main] remove locals for provides_module() return values

2015-11-28T22:00:10+00:00

As of ltluatex, provides_module() has no return value any longer.

[tool,db] make cache directives work again

2015-11-28T14:00:44+00:00

These were rendered unusable due to the suspended initialization.
Creating the directives mapping on the fly is just as good.

[diagnose] adapt invocation of getwritablepath()

2015-11-28T13:58:24+00:00

Some upstream API change (possibly in file.join()) caused that function
to emit relative paths.

    file.join("/foo", "bar") --> good
    file.join("/foo", ""   ) --> good
    file.join("/foo"       ) --> wtf‽

[colors] support pgf transparency in luatex v0.85

2015-11-27T23:53:33+00:00

With tex.scantoks provided by luatex v0.85, now we can
support color transparency in harmony with beamer/pgf/tikz.
No hacking needed at tex macro level, all done in lua code.

[doc,init] clarify default/reference distinction

2015-11-27T23:23:04+00:00

* default:   our package (without lualibs)
* reference: the package from upstream
