I have manually examined all of these diffs and restored a few files that seem to require manual adjustment. The following files still need to be modified manually, in a separate CL: android_sample/SampleApp/AndroidManifest.xml android_sample/SampleApp/res/layout/layout.xml android_sample/SampleApp/res/menu/sample.xml android_sample/SampleApp/res/values/strings.xml android_sample/SampleApp/src/com/skia/sampleapp/SampleApp.java android_sample/SampleApp/src/com/skia/sampleapp/SampleView.java experimental/CiCarbonSampleMain.c experimental/CocoaDebugger/main.m experimental/FileReaderApp/main.m experimental/SimpleCocoaApp/main.m experimental/iOSSampleApp/Shared/SkAlertPrompt.h experimental/iOSSampleApp/Shared/SkAlertPrompt.m experimental/iOSSampleApp/SkiOSSampleApp-Base.xcconfig experimental/iOSSampleApp/SkiOSSampleApp-Debug.xcconfig experimental/iOSSampleApp/SkiOSSampleApp-Release.xcconfig gpu/src/android/GrGLDefaultInterface_android.cpp gyp/common.gypi gyp_skia include/ports/SkHarfBuzzFont.h include/views/SkOSWindow_wxwidgets.h make.bat make.py src/opts/memset.arm.S src/opts/memset16_neon.S src/opts/memset32_neon.S src/opts/opts_check_arm.cpp src/ports/SkDebug_brew.cpp src/ports/SkMemory_brew.cpp src/ports/SkOSFile_brew.cpp src/ports/SkXMLParser_empty.cpp src/utils/ios/SkImageDecoder_iOS.mm src/utils/ios/SkOSFile_iOS.mm src/utils/ios/SkStream_NSData.mm tests/FillPathTest.cpp Review URL: http://codereview.appspot.com/4816058 git-svn-id: http://skia.googlecode.com/svn/trunk@1982 2bbb7eff-a529-9590-31e7-b0007b416f81

/**
|
|
* The following are optional defines that can be enabled at the compiler
|
|
* command line, in a IDE project, in a GrUserConfig.h file, or in a GL custom
|
|
* file (if one is in use). If a GR_GL_CUSTOM_SETUP_HEADER is used they can
|
|
* also be placed there.
|
|
*
|
|
* GR_GL_LOG_CALLS: if 1 Gr can print every GL call using GrPrintf. Defaults to
|
|
* 0. Logging can be enabled and disabled at runtime using a debugger via to
|
|
* global gLogCallsGL. The initial value of gLogCallsGL is controlled by
|
|
* GR_GL_LOG_CALLS_START.
|
|
*
|
|
* GR_GL_LOG_CALLS_START: controls the initial value of gLogCallsGL when
|
|
* GR_GL_LOG_CALLS is 1. Defaults to 0.
|
|
*
|
|
* GR_GL_CHECK_ERROR: if enabled Gr can do a glGetError() after every GL call.
|
|
* Defaults to 1 if GR_DEBUG is set, otherwise 0. When GR_GL_CHECK_ERROR is 1
|
|
* this can be toggled in a debugger using the gCheckErrorGL global. The initial
|
|
* value of gCheckErrorGL is controlled by by GR_GL_CHECK_ERROR_START.
|
|
*
|
|
* GR_GL_CHECK_ERROR_START: controls the initial value of gCheckErrorGL
|
|
* when GR_GL_CHECK_ERROR is 1. Defaults to 1.
|
|
*
|
|
* GR_GL_NO_CONSTANT_ATTRIBUTES: if this evaluates to true then the GL backend
|
|
* will use uniforms instead of attributes in all cases when there is not
|
|
* per-vertex data. This is important when the underlying GL implementation
|
|
* doesn't actually support immediate style attribute values (e.g. when
|
|
* the GL stream is converted to DX as in ANGLE on Chrome). Defaults to 0.
|
|
*
|
|
* GR_GL_ATTRIBUTE_MATRICES: If changing uniforms is very expensive it may be
|
|
* faster to use vertex attributes for matrices (set via glVertexAttrib3fv).
|
|
* Setting this build flag enables this behavior. GR_GL_NO_CONSTANT_ATTRIBUTES
|
|
* must not be set since this uses constant attributes for the matrices.
|
|
* Defaults to 0.
|
|
*
|
|
* GR_GL_USE_BUFFER_DATA_NULL_HINT: When specifing new data for a vertex/index
|
|
* buffer that replaces old data Ganesh can give a hint to the driver that the
|
|
* previous data will not be used in future draws like this:
|
|
* glBufferData(GL_..._BUFFER, size, NULL, usage); //<--hint, NULL means
|
|
* glBufferSubData(GL_..._BUFFER, 0, lessThanSize, data) // old data can't be
|
|
* // used again.
|
|
* However, this can cause a performance decrease on Chrome cmd buffer because
|
|
* it will create a new allocation and memset the whole thing to zero (for
|
|
* security reasons). Defaults to 1 (enabled).
