* Headers/gnustep/gui/NSAffineTransform.h (rotationAngle):
Instance variable removed. Optimize for case of unrotated views.
* Source/NSAffineTransform.m ([+transform]): Do not set rotationAngle.
([+new]): Do not set rotationAngle.
([-appendTransform:]): Do not recompute rotationAngle.
([-init]): Do not set rotationAngle.
([-initWithTransform:]): Do not set rotationAngle.
([-prependTransform:]): Do not compute rotationAngle.
([-rotateByDegrees:]): Do not compute rotationAngle.
([-makeIdentityMatrix]): Do not set rotationAngle.
([-rotateByRadians:]): Do not compute the angle in degrees; do not
compute rotationAngle.
([-setTransformStruct:]): Do not set rotationAngle.
([-scaleTo::]): Optimize out the case of rotated transforms.
([-setFrameRotation:]): Always call -rotationAngle.
([-rotationAngle]): Always compute rotationAngle.
([-concatenateWithMatrix:]): Do not set rotationAngle.
([-boundingRectFor:result:]): Always compute rotationAngle.
