SurfaceFlinger: Select which layer state to visit Modifies the traverseIn[Reverse]ZOrder methods to also take an enum value specifying whether to traverse the current state or the drawing state. This has the effect of fixing a bug where we weren't performing transactions on a child layer because its parent was only visiting its drawing layers (rather than its current layers) and was thus skipping the child, which had not yet been moved from current to drawing. Bug: 36858924 Test: ChildLayerTest.Bug36858924 doesn't hang Change-Id: I1959f40bc07e77864ba024511d429592a398a67a

SurfaceFlinger: Add parent-less relative layering. This is a temporary functionality for the intermediate state where not all child-surface like things in WM land are ported to use Child Surfaces. In particular, we have ported SurfaceView to use child surfaces and relative Z ordering. However the TV frameworks provide a View framework component which overlays views over the SurfaceView but below the main application window. Since we have not ported View framework surfaces to use child layers, there is nothing the WM or View Framework can do about this situation. Luckily the WM API's to have requested this are @hide but we have the one media framework component using it. In order to solve this issue we provide a method to set Z ordering relative to another window without inheriting its coordinate space as a child window would. This way the WM can recognize these TYPE_APPLICATION_MEDIA_OVERLAY windows and Z-order them at -1 with respect to the parents (and the SurfaceView can be at -2). Test: Included in transaction tests. Also manual test of bug repro steps with accomp frameworks/base CL Bug: 36693738 Change-Id: I921852d3d34f67f79ec745b9703f9e679867e7a1

SurfaceFlinger and libgui: Support for child layers. Add support for parenting Layers in a tree. Layers follow scene-graph style rules, that is to say: 1. A child is cropped to the final bounds of the parent. 2. A child inherits the parent's transform (including position) 3. A child's Z ordering is relative to the parent and bounded between the parents siblings. 4. A childs lifetime is bounded by it's parents lifetime. Test: New tests in Transaction_test plus manual testing with later branches. Change-Id: I96f8ad863665b9a70b6f845561344c297b7e6eff

SurfaceFlinger: Use traversal functions to iterate LayerList. In preparation for the Layer hierarchy. There we will need to use such a style to traverse the tree of layers. Test: Just a refactoring. SurfaceFlinger still works. Change-Id: I84dcd82e713f1bdbe911658793ce11460267a956
