Hi Juha-Pekka,
Thanks for considering the earlier suggestions. The solution looks
pretty good, nicely avoids hard-coding of fixed width and height and
making it dependent on the resolution.
I agree with the test as a whole. However I think it requires a slight
change in case of 90/270 rotation for determining the x,y for right and
bottom rectangles.
The suggested change can avoid cropped rectangles, for few resolutions.
Also minute styling issues in a couple of places.
Please find my suggestions inline:

There can be a minor problem of cropping for rectangles right side of
screen, in case of some squarish resolutions.
We know for our multi-plane rotation test for Top Right rectangle:
width = 0.2 hdisplay
height = 0.4 vdisplay
x1 = hdisplay - 0.2hdisplay - 0.1hdisplay (margin)= 0.7hdisplay
y1 = vdisplay - 0.4vdisplay - 0.1vdisplay (margin) = 0.5vdisplay
After rotation 90/270 width and height gets swapped.
Since x1 = 0.7 hdisplay, so maximum width of top-right rectangle without
cropping = 0.3hdisplay.
So if the actual rectangle width after rotation of 90/270 is more than
the maximum available width, we'll get cropped rectangle.
Now due to swap, the width of the rectangle after rotation = 0.4vdisplay.
We will always get cropped rectangle if:
0.4 vdisplay > 0.3hdisplay.
Or in other words we'll get cropped rectangle if hdisplay/vdisplay < 4/3.
Now I am not sure whether we should even think about those resolutions
which have hdisplay:vdisplay < 4:3
But to name a few 1280x1024, 720x576 resolution will get cropped rectangle.
The problem can be solved, if we change the x1 and y1 in case of
rotation 90/270 before swapping.
if (planeinfo[c].rotation_sw & (IGT_ROTATION_90 | IGT_ROTATION_270)) {
x1 = x1 + w - h;
y1 = y1 + h - w;
igt_swap(w, h);
}
so x1 will become 0.7 hdisplay + 0.2hdisplay - 0.4 vdisplay = 0.9
hdisplay + 0.4 vdisplay [ a border/margin of 0.1 hdisplay from right side]
and y1 will become 0.5 vdisplay +0.4 vdisplay - 0.2hdisplay = 0.9
vdisplay + 0.2 hdisplay [a border/margin of 0.1 vdisplay from bottom ]

Sorry for lengthy details for a minor corner case, couldnt make it more
concise, and clear at the same time.
