This class is the basic interface to the X11 (Xlib) graphics system.
It is an implementation of the abstract TVirtualX class.
This class gives access to basic X11 graphics, pixmap, text and font handling routines.
The companion class for Win32 is TGWin32.
The file G11Gui.cxx contains the implementation of the GUI methods of the TGX11 class. Most of the methods are used by the machine independent GUI classes (libGUI.so).
This code was initially developed in the context of HIGZ and PAW by Olivier Couet (package X11INT).

Allocate color in colormap.
If we are on an <= 8 plane machine we will use XAllocColor. If we are on a >= 15 (15, 16 or 24) plane true color machine we will calculate the pixel value using: for 15 and 16 bit true colors have 6 bits precision per color however only the 5 most significant bits are used in the color index. Except for 16 bits where green uses all 6 bits. I.e.:
for 24 bits each r, g and b are represented by 8 bits.
Since all colors are set with a max of 65535 (16 bits) per r, g, b we just right shift them by 10, 11 and 10 bits for 16 planes, and (10, 10, 10 for 15 planes) and by 8 bits for 24 planes. Returns kFALSE in case color allocation failed.

XConvertSelection() causes a SelectionRequest event to be sent to the current primary selection owner.
This event specifies the selection property (primary selection), the format into which to convert that data before storing it (target = XA_STRING), the property in which the owner will place the information (sel_property), the window that wants the information (id), and the time of the conversion request (when). The selection owner responds by sending a SelectionNotify event, which confirms the selected atom and type.
