to use it early
-now we can declare it "const" (as "rasops_isgray[]", while we are here)
-don't use the fg/bg colors in ...alloc_attr() if the WSATTR_WSCOLORS
flag was not given - use reasonable defaults instead
-add an opaque "ri_hw" member to "rasops_info", for driver use
- Don't use int32_t/u_int32_t unless we must.
- Remove C++ single line comment delimeters that crept in.
- Remove defs pertaining to byte granularity 'ragged-edge' bitmasks.
- Move all declarations of per-depth initialization functions to rasops.h.
- Other minor cleanup.
- Re-name rasops_setfont to rasops_reconfig
- Add some new run-time 'features'
- Bring all run-time 'features' under control of rasops_info::ri_flg
- Some cosmetic changes
