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.

do RFNOTEG in initdraw (Anselm Garbe)

Use gcc -ansi -pedantic in 9c. Fix many non-C89-isms.

avoid nil freeimage

debugging help

less graceful shutdown but avoid deadlocks

start with white instead of black

be more faithful to plan 9 environment -- allocate window on top of screen.
