I'm glad you asked.
A TPairSplitter is created in gtkint.pp
in TGtkWidgetSet.CreatePairSplitter.
It is a drawn by the gtk itself (gtkpaned).
A TSplitter is drawn by TCustomSplitter.Paint via the function
DrawSplitter, which is defined in the LCL gtk interface:
gtkwsextctrls.pp TGtkWSCustomSplitter.DrawSplitter.
This method uses the gtk_paint_box function, the same function the gtk
uses itself, except the hpaned and vpaned Detail was exchanged.
I fixed that and now it looks better.

Most interfaces use the TCustomXXX base classes:
Start at TSplitter. This has not much code. Go to TCustomSplitter.
This has a Paint method, which calls
TWSCustomSplitterClass(WidgetSetClass).DrawSplitter(Self);
Use 'Find in Files' and search for DrawSplitter in the gtk directory.
