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)
