Shears the coordinate system.
This change lasts until the next love.draw call, or a love.graphics.pop reverts to a previous love.graphics.push, or love.graphics.origin is called - whichever comes first.
|
In version 0.9.2, a bug caused this function to reset all transformations. It was fixed in 0.10.0. A workaround for 0.9.2 would be to use a combination of rotating and scaling to imitate shearing. |
