Returns the OS's display scale for the window's current display.

float cf_app_get_display_scale(void);

Remarks

On some devices (e.g. Apple Retina or iOS) pixels are clustered in 4x4 packs and abstracted as a single pixel called a "point". The intent is for applications to work in points, and scale their UI elements by a factor of 2x to aid in readability. These devices have very small pixels. Most of the time you should ignore dpi and let the OS handle this. CF enables DPI settings by default, but, you can see if this function returns 2.0f to let you know if pixels are clustered for you under the hood.
