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.
