# Window manager (core.wmgr)
Responsible for managing the main window.

## Modes
The window can be in one of five different modes. Those are:
### `WINDOWED`
A floating window.
### `MINIMIZED`
Minimizes the window to the taskbar/application list/etc..
### `MAXIMIZED`
Maximizes the window.
### `FULLSCREEN`
Hides all decorations and sets the window size to the screen size. Has multi-window support.
### `EXCLUSIVE_FULLSCREEN`
Same as the `FULLSCREEN` mode but has way less overhead at the cost of loosing multi-window support. Has different effects on different platforms:<br/>
**Windows**: *Depending on the video driver, the screen might black out for a few seconds.*<br/>
**macOS**: *Prevents the dock and menu from showing up when hovering over the edge of the screen.*<br/>
**Linux/BSD**: *Disables compositing (transparency effects, window close animation, etc.)*

## Methods
### set_size()
- returns `void`
- description `Updates the window size.`
  - argument `x`
    - type `int`
    - mandatory `yes`
    - description `The new window size (x coordinate).`
  - argument `y`
    - type `int`
    - mandatory `yes`
    - description `The new window size (y coordinate).`
### get_size()
- returns `Vector2i`
- description `Returns the window size.`
### set_position()
- returns `void`
- description `Updates the window position.`
  - argument `x`
    - type `int`
    - mandatory `yes`
    - description `The new window position (x coordinate).`
  - argument `y`
    - type `int`
    - mandatory `yes`
    - description `The new window position (y coordinate).`
### get_position()
- returns `Vector2i`
- description `Returns the window position.`
### set_title()
- returns `void`
- description `Updates the window title.`
  - argument `title`
    - type `String`
    - mandatory `yes`
    - description `The new window title.`
### get_title()

### set_mode()
- returns `void`
- description `Updates the window mode.`
  - argument `mode`
    - type `String`
    - mandatory `yes`
    - description `The new window mode.`
    - format follows `wmgr modes`
### get_mode()
- returns `String`
- description `Returns the window mode.`
### get_fps()
- returns `float`
- description `Returns the current framerate, also known as FPS or frames per second.`
- format `NUMBER.NUMBER` (if argument `flat` is `false`), `NUMBER` (if argument `flat` is `true`) or `INF` if the frame rate is infinite (can be caused if the physics fps is set too high, "should" never occur)
  - argument `flat`
    - type `bool`
    - mandatory `no, default value is false`
    - description `If decimal numbers should be returned or not.`
    - format `If "true" decimal numbers will be removed, if "false" not.`
### get_rendertime()
- returns `float`
- description `Returns how long the last frame took to render (render time).`
### get_delta()
- returns `float`
- description `Returns the latest delta value.`
