The main idea is to make libweston users use the form #include <libweston/libweston.h> instead of the plain #include <compositor.h> which is prone to name conflicts. This is reflected both in the installed files, and the internal header search paths so that Weston would use the exact same form as an external project using libweston would. The public headers are moved under a new top-level directory include/ to make them clearly stand out as special (public API). Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>

/* General overview on how to be a CMS plugin:
|
|
*
|
|
* First, some nomenclature:
|
|
*
|
|
* CMF: Color management framework, i.e. "Use foo.icc for device $bar"
|
|
* CMM: Color management module that converts pixel colors, which is
|
|
* usually lcms2 on any modern OS.
|
|
* CMS: Color management system that encompasses both a CMF and CMM.
|
|
* ICC: International Color Consortium, the people that define the
|
|
* binary encoding of a .icc file.
|
|
* VCGT: Video Card Gamma Tag. An Apple extension to the ICC specification
|
|
* that allows the calibration state to be stored in the ICC profile
|
|
* Output: Physical port with a display attached, e.g. LVDS1
|
|
*
|
|
* As a CMF is probably something you don't want or need on an embedded install
|
|
* these functions will not be called if the icc_profile key is set for a
|
|
* specific [output] section in weston.ini
|
|
*
|
|
* Most desktop environments want the CMF to decide what profile to use in
|
|
* different situations, so that displays can be profiled and also so that
|
|
* the ICC profiles can be changed at runtime depending on the task or ambient
|
|
* environment.
|
|
*
|
|
* The CMF can be selected using the 'modules' key in the [core] section.
