 @{b}drag_save_icons@{ub} Enables displaying Workbench-style transparent icons under the pointer when performing drag saves (ctrl-drag of objects available if NetSurf is running on the Workbench screen) and text selection drags.  If set to 0 the pointer style will change instead.  OS 4.0 users may want to set this to 0 as icons will appear opaque and obscure the drop position.
 @{b}cairo_renderer@{ub} Set rendering engine (SObjs version only). 0 = graphics.library, 1 = Cairo/graphics.library mixed (recommended), 2 = Full Cairo.

+@{b}screen_compositing@{ub} Use compositing on NetSurf's own screen. 0=disable, 1=enable, 2=default
+@{b}redraw_tile_size@{ub} Specify the size of the off-screen bitmap. Higher will speed up redraws at the expense of memory. 0 disables tiling (will use a bitmap at least the size of the screen NetSurf is running on - not recommended)
