New vector-of-component functions: unsafe-flomap-ref*, flomap-ref*, flomap-bilinear-ref*, build-flomap*, inline-build-flomap*;
REPL interaction with -ref* is a bit weird - still need to make flvectors print nicely
Bilinear ref and scaling fix on top and left borders (bad/missing special cases);
Clarified flomap-bilinear-ref docs on extent of interpolated nonzero rectangle
Various doc fixes
Fixed faulty bilinear interpolation in shadow intersection, removed blurring hack
Fixed caching bug (for some reason, generate-temporaries didn't create a unique symbol - note, not *identifier*; used gensym instead)
Please merge into release
Split images/icons/misc into images/icons/symbol and images/icons/misc
Updated tests
Fixed Gtk assertion failure in Macro Stepper (came from "about" dialog being created before the stepper window was shown; fixed by creating it on demand)
Changed Stepper similarly (though there was no assertion failure)
Put a quote in the Macro Stepper logo
Portable recycle-icon
Removed recycle unicode from the docs (was causing PDF build to fail)
Internal API fixes
Please merge into release
Added lambda icon, foot icon, search forward/back icons
Doc fixes
Stepper: icons on buttons, logo and about dialog
Macro stepper: icons on buttons, logo and about dialog
Please merge into release
More documentation (Now contains an animated GIF! We have achieved Web 1.0!)
Fixed stop sign double-rendering bug
Compiled logos size 256 (no rendering time for sizes < 256; intended size almost instantaneous)
Please merge into release
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
Certain unsafe operations were allowed to propagate across a
`lambda' boundary (where space safety is known not to be an issue),
which could lead to duplicate uses of a "once used" variable if
the relevant `lambda' is inlined.
Furthermore, `lambda' boundary crossing wasn't detected in the case
that the operation to propagate was propagated through an intermediate
variable without a `lambda' crossing.
Merge to 5.2.1
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.
