ragg 1.2.2

MacOS: configure script now uses the local system dependencies provided by CRAN via pkg-config. Autobrew libs are used as fallback on non-cran servers only.

ragg 1.2.1

Fix bug that caused R to crash when writing tiff files with transparent background (#97)

Add support for new graphic engine features:
- Arbitrary clipping paths
- Alpha masks
- Linear and radial gradients
- Tiling patterns
Use white as background when passing in a fully transparent background colour to devices that doesn’t support alpha (notably jpeg) (#91)
ragg now defers symbol font resolving to systemfonts which makes it possible to register alternative symbol fonts using register_font() (#90)
Filenames in UTF-8 are now treated correctly on Windows (#87)
Fix size selection of non-scalable fonts when the requested size is bigger than the available

Fix bug in agg_capture() that resulted in premultiplied colour values being returned

Major version release to signify the much improved text support that includes full support for right-to-left scripts and bidirectional text (mix of RtL and LtR scripts). It further adds full support for OpenType features and non-scalable fonts.
Re-exporting register_font(), register_variant(), and font_feature() from systemfonts
Re-exporting get_font_features() from textshaping
Use new textshaping API and handle font fallback correctly
Add support for rendering colour fonts (#1)

Skip text tests on CRAN as no text is plottet on the CRAN solaris machine
Fixed a bug resulting in system crash on certain systems, as well as clang-ASAN error. (#59)

ragg now requires the Harfbuzz and Fribidi libraries to be available when installing from source due to their dependency in the textshaping package.
Move text shaping to the new textshaping package.
Fix agg_capture() on big endian systems (#49, @QuLogic)
Fix use of symbol font on Windows by moving to Segoe UI Symbol which has a Unicode charmap (#51)
Better compatibility with knitr and ggplot2::ggsave()

Roll back support for new clipping options in the graphic engine as it was buggy.

Fix a bug when plotting partially transparent raster (#44)
Add a scaling argument to all devices allowing you to change relative scaling of output.
Horizontal and vertical text are now snapped to the pixel grid in order to improve rendering quality.
Internal changes to prepare for coming updates to the graphic engine

Fix compilation on R <= 3.3 by including Rdynload.h explicitly
Fix a performance regression when plotting text (#33)
Fix erroneous width calculations of strings starting with a space on windows (#32)
Fix a bug in agg_capture() where the output became mangled if device height != width
Fix a bug in raster support where raster data did not get premultiplied before rendering (#38, @yixuan)
Fix an integer overflow issue in the AGG source code

Fix a bug in AGG’s font manager that ignored the font index when it stored and retrieved cached faces

Fix compilation on certain Linux systems by preferring dynamic libraries over static ones (#25, @jimhester).

Avoid a bug when the call to start a device included too many characters (#16)
Fix integer overflow runtime errors in agg source code (agg_scanline_storage_aa.h), by changing storage to long
Remove benchmarking vignettes as it was causing too much trouble on stripped down systems… They are still available on https://ragg.r-lib.org
Better build setup to properly build on all macOS systems
