Summary0006319: Incorrect view/projection matrices in DrawWorld() on develop
DescriptionI don't think matrices stack is set correctly for DrawWorld on develop
Steps To Reproducefunction widget:DrawWorld()

local m1, m2, m3, m4, m5, m6, m7, m8, m9, m10, m11, m12, m13, m14, m15, m16 = gl.GetMatrixData(GL.MODELVIEW)
Spring.Echo("MV", m1, m2, m3, m4, m5, m6, m7, m8, m9, m10, m11, m12, m13, m14, m15, m16)
local p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16 = gl.GetMatrixData(GL.PROJECTION)
Spring.Echo("PJ", p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, p11, p12, p13, p14, p15, p16)

end

At this point the matrix stack only exists to make porting of widgets using gl.{Push,Mult,Pop}Matrix somewhat easier (they can call gl.GetMatrixData(GL.*) to feed whatever matrix is on top to a shader), the engine largely does not manipulate it. The camera transforms can be obtained with gl.GetMatrixData("view") etc.

This is a bit inconsistent, but indeed can be worked around.
