2092	Implement basic dithering for the wide pipeline, v3 Implement basic dithering for the wide pipeline, v3 This patch implements dithering in pixman. A "dither" property is added to BITS images, which is used to: - Force rendering to the image to go through the floating point pipeline. Note that this is different from FAST_PATH_NARROW_FORMAT as it should not enable the floating point pipeline when reading from the image. - Enable dithering in dest_write_back_wide. The dithering uses the destination format to determine noise amplitude. This does not change pixman's behavior when dithering is disabled (the default). Additional types and functions are added to the public API: - The `pixman_dither_t` enum exposes the available dithering methods. Currently a single dithering method based on 8x8 Bayer matrices is implemented (PIXMAN_DITHER_ORDERED_BAYER_8). The PIXMAN_DITHER_FAST, PIXMAN_DITHER_GOOD and PIXMAN_DITHER_BEST aliases are provided and should be used to benefit from future specializations. - The `pixman_image_set_dither` function allows to set the dithering method to use when rendering to a bits image. - The `pixman_image_set_dither_offset` function allows to set a vertical and horizontal offsets for the dither matrix. This can be used after scrolling to ensure a consistent spatial positioning of the dither matrix. Changes since previous version (v2): - linear_gradient_is_horizontal optimization is still compatible with the wide pipeline. The code disabling it was a remnant of a previous patch which performed dithering directly inside linear_get_scanline, and thus needed to be called independently for each scanline. Changes since v1: - Renamed PIXMAN_DITHER_BAYER_8 to PIXMAN_DITHER_ORDERED_BAYER_8 - Disable dithering for channels with 32bpp or more (since they can represent exactly the wide values already). This makes the patches compatible with the newly added floating point format. Dithering is compatible with linear_gradient_is_horizontal	Basile Clement		4 years ago

2090	Fix bilinear filter computation in wide pipeline Fix bilinear filter computation in wide pipeline The recently introduced wide pipeline for filters has a typo which causes it to improperly compute bilinear interpolation positions, causing various glitches when enabled. This patch uses the proper computation for bilinear interpolation in the wide pipeline. It also makes related `if` statements conformant to the CODING_STYLE: * If a substatement spans multiple lines, then there must be braces around it. * If one substatement of an if statement has braces, then the other must too.

2079	meson: store ARM SIMD and NEON tests as text files meson: store ARM SIMD and NEON tests as text files This is unfortunately required to make the tests work correctly, as otherwise meson assumes that the files are C code not assembly. I've opened https://github.com/mesonbuild/meson/issues/5151, to discuss fixing the issue in meson upstream. Fixes #29	Dylan Baker		5 years ago

2074	meson: work around meson issue #5115 meson: work around meson issue #5115 This issue causes openmp arguments to be injected into compilers that can support openmp, even if they don't. This issue will be fixed in 0.51 (code already landed in mesonbuild#5116), for older versions lets work around the issue.	Dylan Baker		5 years ago
