vrld 71317c4359 Add Geometries (replaces Quads).
A Geometry is a collection of vertices describing a non self-intersecting
(simple) polygon. In addition to screen coordinates, the vertices have
attributes for texture coordinates (s,t) and color (r,g,b,a).

It can be used as a quad, to display distorted images, or anything in between.

Added:
^^^^^^

-- geometry from table, where table has the format:
-- info = {
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- {x,y, s,t, [r = 255, g = 255, b = 255, a = 255]}
-- ...
-- }
geom = love.graphics.newGeometry(info)

-- convenience wrapper for quads (same as before)
geom = love.graphics.newQuad(x,y, w,h, sw,sh)

-- retrieve vertex i (1-indexed)
x,y,s,t,r,g,b,a = geom:getVertex(i)

-- set vertex i (1-indexed)
geom:setVertex(i, x,y, s,t, [r,g,b,a])

-- flip geometry
geom:flip(x, y)


Renamed:
^^^^^^^^

love.graphics.drawq() -> love.graphics.drawg()


Removed:
^^^^^^^^

quad:setViewport()
quad:getViewport()
