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
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
