Module draw_list

The draw list lets you create custom graphics within a window.

Each dear imgui window contains its own draw list. You can use Ui::get_window_draw_list to access the current window draw list and draw custom primitives. You can interleave normal widget calls and adding primitives to the current draw list.

Interaction is mostly through the mtehods DrawListMut struct, such as DrawListMut::add_line, however you can also construct structs like Line directly, then call Line::build with a reference to your draw list

There are examples such as draw_list.rs and custom_textures.rs within the imgui-examples directory
