** wglinfo is a small utility that displays all available visuals,
|
|
||||||
** aka. pixelformats, in an OpenGL system along with renderer version
|

||||||
** information. It shows a table of all the visuals that support OpenGL
|
|
||||||
** along with their capabilities. The format of the table is similar to
|
|
||||||
** that of glxinfo on Unix systems:
|
|
||||||
**
|
|
||||||
** visual ~= pixel format descriptor
|
|
||||||
** id = visual id (integer from 1 - max visuals)
|
|
||||||
** tp = type (wn: window, pb: pbuffer, wp: window & pbuffer, bm: bitmap)
|
|
||||||
** ac = acceleration (ge: generic, fu: full, no: none)
|
|
||||||
** fm = format (i: integer, f: float, c: color index)
|
|
||||||
** db = double buffer (y = yes)
|
|
||||||
** sw = swap method (x: exchange, c: copy, u: undefined)
|
|
||||||
** st = stereo (y = yes)
|
|
||||||
** sz = total # bits
|
|
||||||
** r = # bits of red
|
|
||||||
** g = # bits of green
|
|

** b = # bits of blue
