-** visualinfo 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
-** a        = # bits of alpha
-** axbf     = # aux buffers
-** dpth     = # bits of depth
-** stcl     = # bits of stencil
