ff2ed70fa3 color blindness enhancement
This is an attempt at improving the experience of
users with color vision impairement.

At this time this feature can only be enabled for
debugging:

  adb shell service call SurfaceFlinger 1014 i32 PARAM

  with PARAM:
   0 : disabled
   1 : protanomaly/protanopia simulation
   2 : deuteranomaly/deuteranopia simulation
   3 : tritanopia/tritanomaly simulation
  11, 12, 13: same as above w/ attempted correction/enhancement

The enhancement algorithm tries to spread the "error"
such that tones that would otherwise appear similar can be
distinguished.

3da1672acb implement display projection clipping in h/w composer
- cropping to the projection's "viewport" is "simply"
  accomplished by intersecting it with the window crop
  expressed in layerstack space.

4c05dd175e Ensure that viewport and frame are initialized.
onInitializeDisplays() was posting a transaction with changes
to the display projection.  Unfortunately, it only set the
display orientation field and left viewport and frame
uninitialized.

The uninitialized values flowed downstream and found themselves
baked into a bogus DisplayDevice mGlobalTransform.  That transform
was then applied to some Rects which were turned into Regions
that were them combined with other Regions.

Under certain situations, the uninitialized data might have
a largish value, resulting in the creation of Regions with
components in excess of the Region max-value limit of 0x7ffffff
(note that this is not INT_MAX).  Later when performing a
binary operation using the Region, the Spanner would loop
indefinitely trying to figure out how to stuff a humongous
region inside of a max-value region.  Not content to try
just once, the Spanner would continue trying again and
again, pegging the CPU and hanging surface flinger during boot.

Insanity soon followed.

41b6aabf35 fix Surface positions are not floats
Added Surface.setPosition(float, float) which allows to set a surface's
position in float.

ab7c13f96a fix a typo that prevented preserveRects() to work properly
this caused drawing artifacts during the screen rotation
animation of SurfaceView.

29a367bb7c take the state transform into account with h/w composer hal
if the state transform didn't preserve rectangles, we
would still try to use h/w composer hal using the bounds
of the transformed rect, which isn't correct.

now we correctly fall back to composition.

883dffaa00 really fix [3118445] Transform * Transform does not work as expected
Two bugs were counter acting each other.
- rotation matrices are on the left-hand side of multiplies
- the transform of the overlay is applied before that of the layer

0694d0f3b3 fix [3118445] Transform * Transform does not work as expected
The problem wasn't in the multiply operator, but rather in the code
that built the transform from the HAL bitmask.

We now use the multiply operator to build the Transform from the bitmask,
which guarantees, it'll always be correct.

Also added a simple test for Transform.

81bac09fa6 move native services under services/
moved surfaceflinger, audioflinger, cameraservice

all native services should now reside in this location.
