-File: .../x11/server/dix/BuiltInAtoms
-
-This file is of a fixed format and is used to generate both the file
-include/XAtom.h and dix/initatoms.c. Neither of those files should be
-edited directly. Changing the atoms in this file, or even the order in
-which they occur, is equivalent to forcing a new (minor) version number
-on the server. Take care.
-
-The format of the file is that each built in atom starts in column 1
-with no text, other than spaces and tabs, on that line other than a
-mandatory trailing "@" at the end of the line. For each atom (Foo)
-below the defines will be of the form
- #define XA_Foo <n>
-and the string value of the atom will be "Foo".
-
-The comment lines in this file are not guaranteed to be accurate. To see the
-current truth, look at the Xlib documentation as well as the protocol spec.
-
-Atoms occur in five distinct name spaces within the protocol. Any particular
-atom may or may not have some client interpretation within each of the name
-spaces. For each of the built in atoms, the intended semantics and the space
-within which it is defined is indicated.
-
-Those name spaces are
- Property names
- Property types
- Selections
- Font properties
- Type of a ClientMessage event (none built into server)
-
-For the font properties mentioned here, see the spec for more information.

- this mechanism. Anyone else using this sort of IPC mechanism
- should use these properties.
-
- Data is normally fetched and stored out of CUT_BUFFER0; the
- RotateProperties request is used to rotate these buffers.

- pixmap: PIXMAP
-POINT @
- Property type:
- x, y: INT16
-RECTANGLE @
- Property type:
- x, y: INT16

-RESOURCE_MANAGER @
- Property name: (type: STRING)
- Contents of the user's resource manager data base.
-RGB_COLOR_MAP @
- Property type:
- colormap: COLORMAP
- red-max: CARD32
- red-mult: CARD32
- green-max: CARD32
- green-mult: CARD32
- blue-max: CARD32
- blue-mult: CARD32
- base-pixel: CARD32
-
- The fields `red_max', `green_max', and `blue_max' give the maximum
- red, green, and blue values, respectively. Each color
- coefficient ranges from 0 to its max, inclusive. For example,
- a common colormap allocation is 3/3/2: 3 planes for red, 3
- planes for green, and 2 planes for blue. Such a colormap would
- have red_max == 7, green_max = 7, and blue_max = 3. An alternate
- allocation that uses only 216 colors is red_max = 5, green_max =
- 5, and blue_max = 5.
-
- The fields `red_mult', `green_mult', and `blue_mult' give the
- scale factors used to compose a full pixel value. (See next
- paragraph.) For a 3/3/2 allocation red_mult might be 32,
- green_mult might be 4, and blue_mult might be 1. For a
- 6-colors-each allocation, red_mult might be 36, green_mult might
- be 6, and blue_mult might be 1.
-
- The field `base_pixel' gives the base pixel value used to
- compose a full pixel value. Normally base_pixel is obtained
- from a call to XAllocColorPlanes(). Given integer red, green,
- and blue coefficients in their appropriate ranges, one can
- compute a corresponding pixel value with the expression:
-
- r * red_mult + g * green_mult + b * blue_mult + base_pixel
-
- For gray-scale colormaps, only the colormap, red_max, red_mult,
- and base_pixel fields are defined; the other fields are
- ignored. To compute a gray-scale pixel value, use:
-
- gray * red_mult + base_pixel
-
- This is provided to allow applications to share color maps.

-RGB_BEST_MAP @
-RGB_BLUE_MAP @
-RGB_DEFAULT_MAP @
-RGB_GRAY_MAP @
-RGB_GREEN_MAP @
-RGB_RED_MAP @
- Property name: (type: RGB_COLOR_MAP)
- The needs of most applications can be met with five colormaps.
- Polite applications may need only a small RGB space, and can
- use a portion of the default color map. Applications doing
- high-quality RGB rendering will need an entire colormap,
- filled with as large an RGB space as possible, e.g. 332. For
- color separations, an application may need maximum device
- resolution for each of red, green, and blue, even if this
- requires three renderings with three colormaps.
-
- Each of the above five names would be used for sharing color
- maps.
