-// Your shader must contain one function (see the bottom of this file).
-//
-// It should not contain any uniform definitions or anything else, as niri
-// provides them for you.
-//
-// All symbols defined by niri will have a niri_ prefix, so don't use it for
-// your own variables and functions.
-
-// The function that you must define looks like this:
-vec4 open_color(vec3 coords_geo, vec3 size_geo) {
-    vec4 color = /* ...compute the color... */;
-    return color;
-}
-
-// It takes as input:
-//
-// * coords_geo: coordinates of the current pixel relative to the window
-//   geometry.
-//
-// These are homogeneous (the Z component is equal to 1) and scaled in such a
-// way that the 0 to 1 coordinates lie within the window geometry. Pixels
-// outside the window geometry will have coordinates below 0 or above 1.
-//
-// The window geometry is its "visible bounds" from the user's perspective.
-//
-// The shader runs over an area of unspecified size and location, so you must
-// expect and handle coordinates outside the [0, 1] range. The area will be
-// larger than the final window size to accommodate more varied effects.
-//
-// * size_geo: size of the window geometry in logical pixels.
-//
-// It is homogeneous (the Z component is equal to 1).
-//
-// The function must return the color of the pixel (with premultiplied alpha).
-// The pixel color will be further processed by niri (for example, to apply the
-// final opacity from window rules).
-
-// Now let's go over the uniforms that niri defines.
-//
-// You should only rely on the uniforms documented here. Any other uniforms can
-// change or be removed without notice.
-
-// The window texture.
-uniform sampler2D niri_tex;
-
-// Matrix that converts geometry coordinates into the window texture
-// coordinates.
-//
-// The window texture can and will go outside the geometry (for client-side
-// decoration shadows for example), which is why this matrix is necessary.
-uniform mat3 niri_geo_to_tex;
-
-
-// Unclamped progress of the animation.
-//
-// Goes from 0 to 1 but may overshoot and oscillate.
-uniform float niri_progress;
-
-// Clamped progress of the animation.
-//
-// Goes from 0 to 1, but will stop at 1 as soon as it first reaches 1. Will not
-// overshoot or oscillate.
-uniform float niri_clamped_progress;
-
-// Random float in [0; 1), consistent for the duration of the animation.
-uniform float niri_random_seed;
-
-// Now let's look at some examples. You can copy everything below this line
-// into your custom-shader to experiment.
-
-// Example: fill the current geometry with a solid vertical gradient and
-// gradually make opaque.
-vec4 solid_gradient(vec3 coords_geo, vec3 size_geo) {
-    vec4 color = vec4(0.0);
-
-    // Paint only the area inside the current geometry.
-    if (0.0 <= coords_geo.x && coords_geo.x <= 1.0
-            && 0.0 <= coords_geo.y && coords_geo.y <= 1.0)

-        color = mix(from, to, coords_geo.y);
-    }
-
-    // Make it opaque.
-    color *= niri_clamped_progress;
-
-    return color;
-}
-
-// Example: gradually scale up and make opaque, equivalent to the default
-// opening animation.
-vec4 default_open(vec3 coords_geo, vec3 size_geo) {
-    // Scale up the window.
-    float scale = max(0.0, (niri_progress / 2.0 + 0.5));
-    coords_geo = vec3((coords_geo.xy - vec2(0.5)) / scale + vec2(0.5), 1.0);

-    // Get color from the window texture.

-
-    // Make the window opaque.
-    color *= niri_clamped_progress;
-

-
-// Example: show the window as an expanding circle.
-// Recommended setting: duration-ms 250
