Add config options to run different GPU APIs to dm and nanobench Add extended config specification form that can be used to run different gpu backend with different APIs. The configs can be specified with the form: gpu(api=string,dit=bool,nvpr=bool,samples=int) This replaces and removes the --gpuAPI flag. All existing configs should still work. Adds following documentation: out/Debug/dm --help config Flags: --config: type: string default: 565 8888 gpu nonrendering Options: 565 8888 debug gpu gpudebug gpudft gpunull msaa16 msaa4 nonrendering null nullgpu nvprmsaa16 nvprmsaa4 pdf pdf_poppler skp svg xps or use extended form 'backend(option=value,...)'. Extended form: 'backend(option=value,...)' Possible backends and options: gpu(api=string,dit=bool,nvpr=bool,samples=int) GPU backend api type: string default: native. Select graphics API to use with gpu backend. Options: native Use platform default OpenGL or OpenGL ES backend. gl Use OpenGL. gles Use OpenGL ES. debug Use debug OpenGL. null Use null OpenGL. dit type: bool default: false. Use device independent text. nvpr type: bool default: false. Use NV_path_rendering OpenGL and OpenGL ES extension. samples type: int default: 0. Use multisampling with N samples. Predefined configs: gpu = gpu() msaa4 = gpu(samples=4) msaa16 = gpu(samples=16) nvprmsaa4 = gpu(nvpr=true,samples=4) nvprmsaa16 = gpu(nvpr=true,samples=16) gpudft = gpu(dit=true) gpudebug = gpu(api=debug) gpunull = gpu(api=null) debug = gpu(api=debug) nullgpu = gpu(api=null) BUG=skia:2992 Committed: https://skia.googlesource.com/skia/+/e13ca329fca4c28cf4e078561f591ab27b743d23 GOLD_TRYBOT_URL= https://gold.skia.org/search2?unt=true&query=source_type%3Dgm&master=false&issue=1490113005 Committed: https://skia.googlesource.com/skia/+/c8b4336444e7b90382e04e33665fb3b8490b825b Committed: https://skia.googlesource.com/skia/+/9ebc3f0ee6db215dde461dc4777d85988cf272dd Review URL: https://codereview.chromium.org/1490113005
