ImGui_GM v1.0.16

hey all, just a small update for v1.0.16! this update fixes a common crash that would occur when minimizing the window, along with introducing wrappers for the dockbuilding API

Fixed:

• Fixed surface-related crash that would occur when the game was minimized
  • Additionally, the library will no longer send state information to ImGui if the window size is too small or not visible

Added:

• Added wrappers for ImGui.DockBuilder related functions
  • ImGui.DockBuilderDockWindow(window_name, node_id)
  • ImGui.DockBuilderGetNode(node_id)
  • ImGui.DockBuilderGetCentralNode(node_id)
  • ImGui.DockBuilderAddNode(node_id, flags)
  • ImGui.DockBuilderRemoveNode(node_id)
  • ImGui.DockBuilderRemoveNodeDockedWindows(node_id, clear_settings_ref=true)
    
  • ImGui.DockBuilderRemoveNodeChildNodes(node_id)
  • ImGui.DockBuilderSetNodePos(node_id, x, y)
  • ImGui.DockBuilderSetNodeSize(node_id, width, height)
    
  • ImGui.DockBuilderSplitNode(node_id, split_dir, size_ratio_for_node_at_dir)
    
  • ImGui.DockBuilderCopyWindowSettings(src_name, dst_name)
    
  • ImGui.DockBuilderFinish(node_id)
