// The content from common.glsl is automatically prepended to each shader effect. This
// provides the standard input:
// vec2 iTexCoord: Texture coordinates for retrieving the window input color.
// bool uIsFullscreen: True if the window is maximized or in fullscreen mode.
// bool uForOpening: True if a window-open animation is ongoing, false otherwise.
// float uProgress: A value which transitions from 0 to 1 during the animation.
// float uDuration: The duration of the current animation in seconds.
// vec2 uSize: The size of uTexture in pixels.
// float uPadding: The empty area around the actual window (e.g. where the shadow
// is drawn). For now, this will only be set on GNOME.
// Furthermore, there are two global methods for reading the window input color and
// setting the shader output color. Both methods assume straight alpha:
// vec4 getInputColor(vec2 coords)
// void setOutputColor(vec4 outColor)
// Ease-in-out cubic for alpha
