Does anyone have a projection matrix knocking around that will do
y’ = (y/2) - (x/2) + Z
x’ = x + y
z’ = z
My maths is just too poor to figure it out in a reasonable timeframe.
Cas
v’ = M * v for your case looks like this:
x’ 1 1 0 x
( y’ )= ( -0.5 0.5 1 ) * ( y )
z’ 0 0 1 z
resp. for 4x4 GL_PROJECTION matrix.
x’ 1 1 0 0 x
( y’ )= ( -0.5 0.5 1 0) * ( y )
z’ 0 0 1 0 z
w’ 0 0 0 1 w

Relic, you’re a star.
I’ll have a play with it.
