/* Platform-supplied draw functions are either staticly linked, or called via

|
* a vtable. If you want static linking, define DRAW_LINK_DIRECT via a -D
|
|
* option to your compiler, and use the DRAW_FUNC_NAME macro to make your
|
|
* names match what's declared here. Otherwise, if DRAW_LINK_DIRECT is not

|
* defined, you need to create and populate a vtable. See any of the existing
|
|
* platforms' draw implementations for examples.
|
|
*
|
|
* As to how to choose, static linking makes the binary a tiny bit smaller,
|
|
* but vtables give more flexibilty. For example, Palm uses them to support
|
|
* both black-and-white and color screens, while linux on linux separate
|
|
* vtable are created to allow a runtime choice between gtk and ncurses
|
|
* drawing.
