Replaced the old stencil API with love.graphics.drawStencil(stencilfunc), love.graphics.setStencilTest(enable, invert), and love.graphics.getStencilTest.

Draw to the stencil buffer (rather than the color buffer) using love.graphics.drawStencil with a function which draws geometry. Once the stencil buffer has been drawn to, use love.graphics.setStencilTest before drawing to let drawn geometry be affected by it.

love.graphics.clear (and Canvas:clear) will clear both the color and stencil buffers by default. love.graphics.clear("stencil") will clear only the stencil buffer.
