# Tests for 'tablesgg' package

# 21 Nov 2020 / Richard Raubertas
# 27 Nov 2020 : Change list 'tablesggOpt' to function 'tablesggOpt()'.  (Now 
#               diverging from 'tests_1.r'.)
# 02 Feb 2021 : Replace 'grProps' with 'grSpecs'.
# 22 Feb 2021 : Run tests with 'allowMarkdown=FALSE'.  More 'tablesggOpt' tests.
# 04 Mar 2021 : Orthogonality of styles and scale.
# 25 Apr 2021 : More thorough test of 'scale'.
# 24 Jan 2024 : Change deprecated 'size' arg to 'element_rect' to 'linewidth'.
