R: Convert a grob to device calls

grobToDev {gridSVG} | R Documentation

## Convert a grob to device calls

### Description

This function is used to make calls to a device to draw a grob. It is generic so new grob classes can write their own methods.

### Usage

    grobToDev(x, dev)

### Arguments

`x` | A grob.
`dev` | A graphics device.

### Details

This function is not called directly by the user. It is exposed so that new grob classes can easily write their own methods which call existing methods for standard grobs.

The difference between this function and `primToDev()` is that this one takes care of setting up coordinate systems based on the grid viewports so that SVG output is positioned correctly, then it calls `primToDev()` to produce the actual SVG elements.
