-Skia Debugger (deprecated)
-=============
-
-Introduction
-------------
-
-The Skia Debugger is a graphical tool used to step through and analyze the
-contents of the Skia picture format. Pre-requisites include installing the Qt
-Library and downloading the Skia code base.
-
-Qt is available here: http://qt-project.org/downloads.
-
-It can also be installed on linux using 
-
-<!--?prettify?-->
-~~~~
-sudo apt-get install libqt4-dev
-~~~~
-
-Note that the debugger has been tested with Qt 4.8.6; it is known not to work
-with Qt 5.0RC1 on the Mac.
-
-Design Documents:
-
-https://docs.google.com/a/google.com/document/d/1b8muqVzfbJmYbno9nTv5721V2nlFMfnqXYLNHiSQ4ws/pub
-
-
-How to build and run
---------------------
-
-Because the debugger uses Qt, you'll need to build skia in 64 bit mode:
-
-<!--?prettify?-->
-
-    GYP_DEFINES="skia_arch_width=64" python bin/sync-and-gyp
-    ninja -C out/Debug debugger
-    out/Debug/debugger
-
-For Windows, Qt ships as 32 bit libraries so to build and run one should just be
-able to:
-
-<!--?prettify?-->
-~~~~
-cd trunk
-make clean gyp
-<open solution in VS2010 and build everything>
-~~~~
-
-Depending on how your Qt is installed you may also need to define an environment
-variable like: 
-
-~~~~
-GYP_DEFINES=qt_sdk='C:\Qt\4.8.6\'
-~~~~
-(which needs to be set before you execute 'make gyp')
-
-On Windows, you may need to copy several DLL and PDB files from %QTDIR%\bin into
-your executable directory (out/Debug or out/Release):
-
-QtCore4.dll QtCored4.dll QtCored4.pdb
-
-QtGui4.dll QtGuid4.dll QtGuid4.pdb
-
-QtOpenGL4.dll QtOpenGLd4.dll QtOpenGLd4.pdb 
-
-
-Producing SKPs for usage
-------------------------
-
-You may either use the Skia testing images (GMs) for use in the debugger or
-create your own via chromium.
-
-To create SKPs from Chromium you must download and build chromium on your
-platform of choice: http://www.chromium.org/Home
-
-<!--?prettify?-->
-~~~~
-cd src
-make chrome
-out/Debug/chrome --no-sandbox --enable-gpu-benchmarking --force-compositing-mode
-~~~~
-
-After which go to Tools, Settings, Javascript Console and type:
-
-<!--?prettify?-->
-~~~~
-chrome.gpuBenchmarking.printToSkPicture(dirname)
-~~~~
-
-Using the Debugger
-------------------
-
-The debugger is fairly straight forward to use once a picture is loaded in. We
-can step through different commands via the up and down keys, and clicking on
-the command in the list. We can pause execution of commands with the pause
-button in order to inspect the details of the command in the inspector tabs
-down below.
-
- 
- Command      | Function
- -------------|-----------------------------------------------
- x            | toggles the visibility of the selected command
- alt-x        | clears all hidden commands
- ctrl-x       | shows all deleted commands
- b            | creates a breakpoint on a command
- alt-b        | clears all breakpoints
- ctrl-b       | shows all breakpoints
- ctrl-r       | rewinds the picture to the first command
- ctrl-p       | plays to the next breakpoint or last command
- ctrl-i       | Toggles the inspector and settings widgets
- ctrl-d       | Toggles the directory widget
- space        | Pauses drawing execution
- ctrl-o       | Opens a file dialog for loading pictures
- ctrl-s       | Saves the skp if you deleted any commands
- ctrl-shift-s | Saves the skp under the new specified name
- ctrl-q       | Quits
