[PATCH] xrandr: Simplify transform and scale code

[Éric Piel]

Hello,
While reading the code of xrandr, I noticed some little possible
optimizations. Here they are :-)

The init_transform() function sets up a unit matrix, so only the scaling
factors need to be updated. Additionally, the code for the transform
option initialised twice the matrix, which is not needed.
