Began scribble docs
Added `compiled-bitmap' and `compiled-bitmap-list', which embed bitmaps
computed at expansion time into compiled files (safe 3D values)
Please merge into release
(cherry picked from commit 4d1cedc913)
This removes all the SVG sources, parsing, and marked-layer colorizing, the PNG binaries in the distribution, and the dependence of DrRacket on `slideshow/pict'.
Icons are now produced by drawing on a bitmap-dc%, inferring or building a z map, choosing a material, and sending these to a two-pass ray tracer. This is for the most part hidden behind an API consisting of functions from colors and optional sizes and materials to `bitmap%'s.
Contracts and documentation forthcoming.
- SVG icon sources
- Playback-style icons, logos, stop signs, magnifying glasses, etc., in diffuse and shiny styles
- Program to pre-render SVG files (icons/private/svg/render-png.rkt)
- Pre-rendered icons (PNGs in power-of-2 sizes)
- Made `icons' a module, with functions to conveniently load icons and convert to/from picts
- Scribble docs for `icons'
- Used new icons in DrRacket toolbar
