Subject: [PATCH xf86-video-mach64 4/4] Fix compositing rotation
|
|
|
|
This corrects the composite operation's interpretation of a
|
|
source picture transformation matrix indicating rotation,
|
|
correcting a previous behavior where the source image was simply
|
|
flipped and not rotated. This is done by using a transformed vector
|
|
for each vertex of the source rectangle, instead of just two at
|
|
each of the diagonally opposed corner vertices.
