Without this, the dim "fade" will start at the top of the untrimmed actor. With
a large enough draggable_border_width setting, this will show no fade at all.

The way the window dimmer shader is applied will cause rendering errors with
the rounded corners, invisible borders or shaped textures since it doesn't deal
well with the multitexturing used by the MetaShapedTexture. Use an off-screen
buffer to flatten the texture before being applied.

The shader currently forces GLSL 1.0 to avoid being incompatible with older hardware but is still using features not available in 1.0.
Strict compilers fail to compile the shader:
error C7506: OpenGL/ES does not define the global variable gl_TexCoord
As every hardware/driver that supports 1.0 also supports 1.10 bumping the version to fix it is safe.

Override the new mutter preference /apps/mutter/general/attach_modal_dialogs
to attach modal dialogs to their parent window. Animate the modal dialogs
expanding from the top of the parent window. Slowly dim the parent window
after the dialog comes up.
