### Description

Implement https://github.com/wlrfx/scenefx

```c
/* available options */

static const int opacity = 0; /* flag to enable opacity */
static const float opacity_inactive = 0.5;
static const float opacity_active = 1.0;

static const int shadow = 1; /* flag to enable shadow */
static const int shadow_only_floating = 0; /* only apply shadow to floating windows */
static const struct wlr_render_color shadow_color = COLOR(0x0000FFff);
static const struct wlr_render_color shadow_color_focus = COLOR(0xFF0000ff);
static const int shadow_blur_sigma = 20;
static const int shadow_blur_sigma_focus = 40;
static const char *const shadow_ignore_list[] = { NULL }; /* list of app-id to ignore */

static const int corner_radius = 0; /* 0 disables corner_radius */
static const int corner_radius_inner = 3; /* 0 disables corner_radius */
static const int corner_radius_only_floating = 0; /* only apply corner_radius and corner_radius_inner to floating windows */

static const int blur = 1; /* flag to enable blur */
static const int blur_optimized = 1;
static const int blur_ignore_transparent = 1;
static const struct blur_data blur_data = {
	.radius = 5,
	.num_passes = 3,
	.noise = 0.02,
	.brightness = 0.9,
	.contrast = 0.9,
	.saturation = 1.1,
};
```

> **NOTE:** If you are using nix with flakes, scenefx has a flake for scenefx https://github.com/wlrfx/scenefx/blob/main/flake.nix

> **NOTE:** Blur doesn't work on windows with opacity set (opacity_active, opacity_inactive)

> **NOTE:** In DWL's Makefile `scenefx` must be placed before `wlroots-0.18`, e.g. `PKGS = scenefx wlroots-0.18 wayland-server ...`
