Image version 0.59.1

Deprecation

• The option :fontfile to Image.Text.text/2 is deprecated in favour of :font_file to be compatible with other functions that use the same option name.

Bug Fixes

• Remove pattern matching on Stream.t in Image.open/2. Thanks to @dcrck for the PR. Closes #187.

• Fix Image.Text.text/2 when :height is specified but not :width. In this case an error is returned since :height can only be specified if :width is also specified. Thanks to @Neophen for the report. Closes #185.

• Fix Image.Text.text/2 when the option :font_weight is specified. The options :font_weight and :letter_spacing are implemented by wrapping the text in a Pango markup span tag. If the string parameter starts with <span then these two options are ignored since this implies the user is taking full control of the markup. Closes #183.

• Add option documentation for :font_file to Image.Text.text/2 and note the requirement to also specify :font if :font_file is specified.

• Clarify that Image.Text.text/2 option :font_file is not supported on MacOS. On that platform, only FontBook fonts are supported. It is known to work on Linux. The status on Windows is currently unknown by the author - feedback would be welcome.
