Shear tool is used to shift one part of an image, a layer, a
selection or a path to a direction and the other part to the
opposite direction. For instance, a horizontal shearing will shift
the upper part to the right and the lower part to the left. A
rectangle becomes a diamond. This is not a rotation: the image is
distorted. To use this tool after selecting, click on the image or
the selection: a grid is surperimposed and the Shearing Information
dialog is opened. By dragging the mouse pointer on the image you
distort the image, horizontally by default (x direction). To shear
vertically press <span><b class="keycap">Shift</b></span> and click on the grid (this
operation is not well perfected). When you are satisfied, click on
the <span class="guilabel">Shear</span> button in the info dialog to
validate.
