Capabilities
*These enumerated types are supported through the GLX client-side API library, but there are currently no HP X Server GLX
visuals with these capabilities. They can still be used to query any Server and will operate properly if connected to a
non-HP server with GLX support for these visual capabilities.
The enumerated types listed below can be used only through glXGetConfig when it is known
that the GLX visual being queried supports transparency or in other words, has a
GLX_TRANSPARENT_TYPE_EXT property other than GLX_NONE_EXT.
