* Support BGR with DirectWrite.Gravatar bungeman2015-03-19

* Factor text size device mapping in SkScalerContext.Gravatar bungeman2014-12-05
| | | | | | | | | | | | | All of our font back-ends use the text size in some way other than simple concatentation with the current matrix. The code here finds the full device matrix and then decomposes it to extract the text size. FreeType, GDI, and DirectWrite use the text size as the pre-hint scale. CoreText will not scale color emoji above the requested text size, and certain features like 'trak' are performed on the text size. Review URL: https://codereview.chromium.org/748883005

* Detect presence of dwrite_1.h.Gravatar bungeman2014-09-10
| | | | | | | | | | | | | | | | | | This introduces the SK_HAS_DWRITE_1_H define which may be set at build time or will be true when WINVER_MAXVER >= 0x0602 . The dwrite_1.h header is available starting in Windows SDK 8.0. This change supports users who must still use Windows SDK 7.0. It also allows for easier local testing of the older interfaces on newer versions of Windows.

* Fix error handling in DirectWrite with tiny text.Gravatar bungeman2014-08-28
| | | | | | | | | | | If there is an error while trying to determine the metrics, we need to bail instead of potentially using uninitialized data. R=reed@google.com, mtklein@google.com Author: bungeman@google.com Review URL: https://codereview.chromium.org/511783003
* DirectWrite to use aliased if ClearType is empty.Gravatar Ben Wagner2014-08-27
| | | | | | | | | | | | | | | | | Some CJK fonts with some versions of DirectWrite return valid data for bitmaps, but not for cleartype data. For reference, two screenshots. M37 Stable and then with this patch: http://imgur.com/9pf3rB9,EiTb6Li See https://code.google.com/p/chromium/issues/detail?id=396624#c10 for content of test html file.

| | | | This flag is no longer defined anywhere, so remove it's use.
* DirectWrite to detect GDI only fonts.Gravatar bungeman2014-06-30
| | | | | | | | | | | | | | The exist a number of webfonts which have poor hinting which look very bad with any vertical subsampling. The fonts often rely on drop out control to avoid zero coverage in the y direction. As a result, any font with hints but no 'gasp' table is considered to be poorly hinted in this way, and will not be rendered with vertical subsampling when hinted.

* Better rendering detection with DirectWrite.Gravatar bungeman2014-06-23
| | | | | | | | | | | When requesting embedded bitmaps, all sizes in a gridfit gasp range with a bitmap in that range should be gridfit to the fullest extent possible.

* DirectWrite to not round already subpixel metrics.Gravatar bungeman2014-06-20
| | | | | | | | | | | | | | | | In keeping with the FreeType and Mac scaler contexts, do not artificially round already subpixel metrics. The subpixel flag should be the 'forceSubpixel' flag when it comes to metrics. Existing backends will give subpixel metrics when 'subpixel' is requested, but will not round proper metrics when 'subpixel' is not requested.
