* Make GPU coord transforms automaticGravatar bsalomon@google.com2013-10-02
| | | | | | | | | | | | | Adds a GrCoordTransform class and updates the framework to handle coord transforms similar to how it handles textures with GrTextureAccess. Renames GrGLEffectMatrix to GrGLCoordTransform and slightly repurposes it to be used by the framework instead of effects.

| | | | | | | | | | | | | | | | | We're writing fDone without holding the mutex. Bad form, says tsan. In practice this is fairly innocuous, as fDone only ever goes from false to true and only once.

* Add an option on SkImageDecoder to skip writing 0s.Gravatar scroggo@google.com2013-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Only implemented for PNG. Add a getter and setter, and sets the default to false in the constructor. Also copies the setting in copyFieldsToOther. Fix an indpendent bug where fDitherImage was not being copied in copyFieldsToOther. In SkScaledBitmapSampler::begin, consolidate the settings passed in by passing a const reference to the decoder. The decoder can be referenced for its settings of dither, unpremultiplied, and now skipping writing zeroes. Update callers to use the new API. In png decoder, rather than passing around a pointer to an initial read of getDitherImage, and potentially changing it, look at the field on the decoder itself, and modify it directly. This is a change in behavior - now if that same decoder is used to decode a different image, the dither setting has changed. I think this is okay because A) the typical use case is to use a new decoder for each decode, B) we do not make any promises that a decode does not change the decoder and C) it makes the code in SkScaledBitmapSampler much cleaner. In SkScaledBitmapScampler, add new row procs for skipping zeroes. Now that choosing the row proc has five dimensions (src config, dst config, dither, skip writing zeroes, unpremultiplied), use a new method: each src/dst combination has a function for choosing the right proc depending on the decoder. SkScaledBitmapScampler::RowProc is now public for convenience. Remove Sample_Gray_D8888_Unpremul, which is effectively no different from Sample_Gray_D8888. In cases where unpremultiplied was trivial, such as 565 and when sampling from gray, decoding may now succeed. Add a benchmark (currently disabled) for comparing the speed of skipping writing zeroes versus not skipping. For this particular image, which is mostly transparent pixels, normal decoding took about 3.6 milliseconds, while skipping zeroes in the decode took only about 2.5 milliseconds (this is on a Nexus 4). Presumably it would be slower on an image with a small amount of transparency, but there will be no slowdown for an image which reports that it has no transparency. In SkImageRef_ashmem, always skip writing zeroes, since ashmem memory is guaranteed to be initialized to 0. Add a flag to skip writing zeroes in skimage. Add a regression test for choosing the rowproc to ensure I did not change any behavior accidentally.

* Mark when effects and programs have vertex codeGravatar commit-bot@chromium.org2013-09-30
| | | | | | | | | | | | | | | | Adds a 'hasVertexCode' method to GrEffect and a 'fHasVertexCode' field to GrGLProgramDesc::KeyHeader. Also adds a GrVertexEffect class that effects have to inherit from in order to set the 'hasVertexCode' flag and be able to emit vertex code, and updates the existing effects to use it as needed.

They either always need one or never do. Also removes kCustom_CoordsType from the CoordsType enum in GrEffect (that enum is really only meant for coords provided by the framework), and updates GrSimpleTextureEffect::TestCreate to make the effect with position as well, instead of just local coords.

* Map Calibri to CarlitoGravatar bungeman@google.com2013-09-20
| | | | | | | | | | | | | | | Chrome OS will have Carlito as a metric-compatible replacement for Calibri. This change has to be combined with a Chrome OS change to add Calibri and configure fontconfig accordingly. BUG=280557 TEST=With the CrOS change, a page using Calibri will use Carlito instead of the default fallback font (Arimo in case of English UI).

* Fix slight hinting with GDI.Gravatar bungeman@google.com2013-09-20
| | | | | | | | | | | Sometimes GDI manages to return a different number of points for hinted and non-hinted outlines. This change handles that case and falls back to non-hinted. This does not re-enable slight hinting, so there should be no observable difference in tests. There are still issues with 'D' in some font/size combinations where 'flips' are used. git-svn-id: http://skia.googlecode.com/svn/trunk@11417 2bbb7eff-a529-9590-31e7-b0007b416f81
