wordcloud: Internal function for textplot_wordcloud
In quanteda.textplots: Plots for the Quantitative Analysis of Textual Data

This function implements wordcloud without dependencies. Code is adopted from wordcloud::wordcloud().

`x`	a dfm or quanteda.textstats::textstat_keyness object
`min_size`	size of the smallest word
`max_size`	size of the largest word
`min_count`	words with frequency below min_count will not be plotted
`max_words`	maximum number of words to be plotted. The least frequent terms dropped. The maximum frequency will be split evenly across categories when `comparison = TRUE`.
`color`	colour of words from least to most frequent
`font`	font-family of words and labels. Use default font if `NULL`.
`adjust`	adjust sizes of words by a constant. Useful for non-English words for which R fails to obtain correct sizes.
`rotation`	proportion of words with 90 degree rotation
`random_order`	plot words in random order. If `FALSE`, they will be plotted in decreasing frequency.
`random_color`	choose colours randomly from the colours. If `FALSE`, the colour is chosen based on the frequency
`ordered_color`	if `TRUE`, then colours are assigned to words in order.
`labelcolor`	colour of group labels. Only used when `comparison = TRUE`.
`labelsize`	size of group labels. Only used when `comparison = TRUE`.
`labeloffset`	position of group labels. Only used when `comparison = TRUE`.
`fixed_aspect`	logical; if `TRUE`, the aspect ratio is fixed. Variable aspect ratio only supported if rotation = 0.
`scale`	deprecated argument
`min.freq`	deprecated argument

`random.order`	deprecated argument
`random.color`	deprecated argument
`rot.per`	deprecated argument
`ordered.colors`	deprecated argument
`use.r.layout`	deprecated argument
`fixed.asp`	deprecated argument
`...`	additional parameters. Only used to make it compatible with wordcloud
