* Consolidate GPU buffer implementationsGravatar cdalton2016-03-25
| | | | | | | | | | | | | | | | Consolidates all the different buffer implementations into a single GrBuffer class. This will allow us to add new buffer types, use DSA in OpenGL, track buffer bindings by unique ID, cache buffers without respect to the type of data they have been used for previously, etc. This change is strictly a refactor; it introduces no change in functionality.

* sRGB support in Ganesh. Several pieces:Gravatar brianosman2016-03-21
| | | | | | | | | | | | | | | | | | | | | | sRGB support now also requires GL_EXT_texture_sRGB_decode, which allows us to disable sRGB -> Linear conversion when reading textures. This gives us an easy way to support "legacy" L32 mode. We disable decoding based on the pixel config of the render target. Textures can override that behavior (specifically for format-conversion draws where we want that behavior). Added sBGRA pixel config, which is not-really-a-format. It's just sRGBA internally, and the external format is BGR order, so TexImage calls will swizzle correctly. This lets us interact with sRGB raster surfaces on BGR platforms. Devices without sRGB support behave like they always have: conversion from color type and profile type ignores sRGB and always returns linear pixel configs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the "path stroke error bound" path parameter to 0.02 for all paths. This means that the stroked path area will be within 98% of the stroke width in path space. This should fix many cases where NVPR stroked paths were visibly different to Skia stroked paths. One such path is in dashcubics gm. This increases the amount of subdivisions the path object creation will make for paths that need it. This in turn will increase gpu object space requirements sligthly. Both of these effects should be unnoticeable. GL_NV_path_rendering.txt: """ Every path object has a stroke approximation bound parameter (PATH_STROKE_BOUND_NV) that is a floating-point value /sab/ clamped between 0.0 and 1.0 and set and queried with the PATH_STROKE_BOUND_NV path parameter. Exact determination of samples swept an orthogonal centered line segment along cubic Bezier segments and rational quadratic Bezier curves (so non-circular partial elliptical arcs) is intractable for real-time rendering so an approximation is required; /sab/ intuitively bounds the approximation error as a percentage of the path object's stroke width. Specifically, this path parameter requests the implementation to stencil any samples within /sweep/ object space units of the exact sweep of the path's cubic Bezier segments or partial elliptical arcs to be sampled by the stroke where sweep = ((1-sab)*sw)/2 where /sw/ is the path object's stroke width. The initial value of /sab/ when a path is created is 0.2. In practical terms, this initial value means the stencil sample positions coverage within 80% (100%-20%) of the stroke width of cubic and rational quadratic stroke segments should be sampled.

| | | | | | | | | This allows us to create distance field textures with better precision, which may help text quality. BUG=skia:3103 Review URL: https://codereview.chromium.org/762923003
* Implement conics for NVPRGravatar kkinnunen2014-11-19
| | | | | | | | | Implement conics for NVPR. Verified with currently disabled conicpaths gm, produces mostly same shapes with nvprmsaa4 and msaa4. BUG=skia:2033 Review URL: https://codereview.chromium.org/694503003
* Remove unused NVPR related GL tokensGravatar kkinnunen2014-11-18
| | | | | | | | | | | | | | Remove unused NVPR related GL tokens. Also replace GR_GL_PATH_INITIAL_END_CAP and GR_GL_PATH_TERMINAL_END_CAP with a single call setting GR_GL_PATH_END_CAPS. Skia does not and probably will not have different initial and terminal caps. This came up in the review of command buffer implementation of the extension. If more NVPR features will be used, the respective tokens can be added back per implemented feature. Review URL: https://codereview.chromium.org/723453002

* Implement NV_path_rendering on OpenGL ESGravatar kkinnunen2014-08-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement support for NV_path_rendering on OpenGL ES. Use glProgramPathFragmentInputGenNV function call instead of glPathTexGenNV to communicate transforms to fragment shader. The intention is that the NVPR paths will be drawn with the same shader program as non-NVPR geometry. For NVPR calls, the GPU will skip the vertex shader and just run the fragment shader. After program is linked, query the locations of the fragment shader inputs with glGetResourceLocation. The location will be used to set the transforms with glProgramPathFragmentInputGenNV. The functions and their workings are documented in: glProgramPathFragmentInputGenNV https://www.opengl.org/registry/specs/NV/path_rendering.txt (note: addition as of API version 1.3) glGetResourceLocation https://www.opengl.org/registry/specs/ARB/program_interface_query.txt http://www.opengl.org/registry/doc/glspec44.core.pdf (function is in core Open GL 4.4) Note: glProgramPathFragmentInputGenNV could be used also for OpenGL. However, using seems to trigger a bug in the driver. Disable this feature on OpenGL at least until the driver is fixed and released. The bug manifests in shadertext test, where the lower-left text pair is missing. Valgrind catches a bad read for the test and causes the context to OOM reproducibly.
