A *tiny*, portable, immediate-mode UI library written in ANSI C

## Features
* Tiny: around `1100 sloc` of ANSI C
* Works within a fixed-sized memory region: no additional memory is allocated
* Built-in controls: window, scrollable panel, button, slider, textbox, label,
  checkbox, wordwrapped text
* Works with any rendering system that can draw rectangles and text
* Designed to allow the user to easily add custom controls
* Simple layout system

## Example

```c
if (mu_begin_window(ctx, "My Window", mu_rect(10, 10, 140, 86))) {
  mu_layout_row(ctx, 2, (int[]) { 60, -1 }, 0);

mu_label(ctx, "First:");
  if (mu_button(ctx, "Button1")) {
    printf("Button1 pressed\n");
  }

mu_label(ctx, "Second:");
  if (mu_button(ctx, "Button2")) {
    mu_open_popup(ctx, "My Popup");
  }

if (mu_begin_popup(ctx, "My Popup")) {
    mu_label(ctx, "Hello world!");
    mu_end_popup(ctx);
  }

mu_end_window(ctx);
}
```

## Usage
* See [`doc/usage.md`](doc/usage.md) for usage instructions
* See the [`demo`](demo) directory for a usage example

## Notes
The library expects the user to provide input and handle the resultant drawing
commands, it does not do any drawing itself.

## Contributing
The library is designed to be lightweight, providing a foundation to which you
can easily add custom controls and UI elements; pull requests adding additional
features will likely not be merged. Bug reports are welcome.
