INSTALL: set $NPROC on macOS My MacBook Pro has hw.ncpu=12, so set NPROC=12. Speeds up INSTALL dramatically. Should probably add similar code to other OSes. Also silence rio warning from earlier commit.

libdraw: redo default font construction to be hidpi-safe If $font is not set, the default font is constructed from font data linked into every libdraw binary. That process was different from the usual openfont code, and so it was not hidpi-aware, resulting in very tiny fonts out of the box on hidpi systems, until users set $font. Fix this by using openfont to construct the default font, by recognizing the name *default* when looking for font and subfont file contents. Then all the hidpi scaling applies automatically. As a side effect, the concept of a 'default subfont' is gone, as are display->defaultsubfont, getdefont, and memgetdefont.

file: recognize Mach-O binaries and Java class files

file: add missing newlines to file types

paint: add drawing program from 9front (#112) Paint first appeared in 9front. The 9front license is reproduced in the related source files - the original repository is located at https://code.9front.org/hg/plan9front.

rio: make 'mk all' explain why it does nothing on non-x11 systems Fixes #98.

devdraw: remove os x 10.5 compatibility code

unix: fix tar use in mkfile to allow Plan 9 tar

acme: add 32x32 boxcursor The only difference from the upscaled 16x16 is a one-pixel adjustment in the offset position, but this at least exercises setcursor2.

INSTALL: set CC9 on macOS to use xcrun clang Using plain 'clang' does not work well for the new devdraw on macOS 10.14. But 'xcrun --sdk macosx clang' does work, for reasons no one understands. Hopefully this will be OK on all macOS systems.

devdraw: add Cursor2 support on macOS 10.14 Mojave This replaces the pixel-art scaling algorithm used for upscaling before. The results were not crisp enough to serve as everyday cursors.

tweak: add support for Cursor2

libdraw: add Cursor2, a 32x32 high-res cursor Also add setcursor2, esetcursor2, and draw protocol encoding. Calls to the old setcursor, esetcursor create a 32x32 by pixel doubling when needed.

devdraw: rewrite the Cocoa screen using Metal Add a new macOS cocoa screen, cocoa-screen-metal.m. Rewrite the macOS cocoa drawing code to use the builtin runloop, and use Metal to push pixels with CAMetalLayer. Remove all of the deprecated code, and simplify some of the logic. Modify mkwsysrules.sh such that the new code is used only when the system version is equal or higher than 10.14. Allow touch events to simulate mouse clicks: three finger tap for the middle mouse button; four finger tap for the 2-1 chord. Support Tresize. Scale 16x16 Cursor up to 32x32 with an EPX algorithm. Support macOS input sources including the basic dead keys and the advanced CJK input methods. Increase the communication buffers in cocoa-srv.c to allow more input, especially for long sentences prepared by the macOS input souces.

upas/smtp: fix TLS connections (#163) Both `upas/nfs` and `upas/smtp` call the currently broken `tlsClient()` from libsec. This commit copies a fix from upas/nfs into upas/smtp. In `imapdial()`, upas/nfs replaces a process call for tlsClient with `stunnel3` when not on Plan 9. upas/smtp calls tlsClient directly as a function, so imapdial was copied into mxdial.c as `smtpdial()`, and tlsClient+dial replaced with a call to smtpdial.
