* Remove 1/2 pixel offsets for distance field layout.Gravatar commit-bot@chromium.org2014-05-21
| | | | | | | | | | | | | The 1/2 pixel offsets are for rounding when snapping the glyphs to integer boundaries. Since we're using subpixel layout and sampled textures, we shouldn't snap to integer boundaries.

* Add CPU backing store for GrAtlas to reduce texture uploads.Gravatar commit-bot@chromium.org2014-05-14
| | | | | | | | | | | | | | | | | | This change creates a temporary copy of each GrPlot on the CPU side. As we add glyphs to a plot, a dirty rectangle is tracked, and just before we render text we upload all of the dirty areas to the atlas texture. Once a plot is nearly full, we assume that we may only be adding one or two glyphs before rendering, so we delete the CPU backing memory to save space, and upload directly.

* Fix artifacts in distance field rendering due to bilerpGravatar commit-bot@chromium.org2014-04-15
| | | | | | | | | | | | | | | | | Because we were using the full distance field glyph rect, there were cases when a neighboring texel might be set to full value (e.g. we might copy the glyph over old data after a purge). This was giving artifacts, and insetting the rect by 1 solves the problem. In doing this, I discovered that removing the extra 1 texel pad around the glyph meant to handle bilerp, and insetting by 2, works just as well and saves space in the glyph atlas.

* Move distance field generation to the glyph cache.Gravatar commit-bot@chromium.org2014-04-14
| | | | | | | | | | | | | | Distance fields are currently created in GrTextStrike, which is the wrong place. This moves that to the glyph cache where it belongs. As part of my testing, I found that when we fall back to paths in the GrDistanceFieldTextContext it was not scaling them properly, so that's fixed in here too.

| | | | | | | | | | | | | LCD support is handled by shifting the uv coordinate by 1/3 of a pixel (transformed by the inverse CTM) to the left and right of the original texture coordinate, and using left, center, and right lookups to set the RGB values.

* Move distance field font code into GrDistanceFieldTextContext.Gravatar commit-bot@chromium.org2013-12-19
| | | | | | | | | | | | | | This avoids the SkDraw path and renders the distance field glyphs directly from GrDistanceFieldTextContext. It also disables LCD, subpixel and autohinting, and removes the supporting code when rendering DF fonts.
