This directory contains `rasops', a set of raster operations intended to
replace the dev/rcons/raster stuff for both wscons and rcons. It yields
significantly improved performance, supports multiple depths and color.

Issues/TODO:

- There is no generic `putchar' function for 2bpp
- Color handling for 2bpp is broken
- copycols() from rasops_bitops.h is broken in right->left case
- The stamp mutex is not particularly safe
- 64-bit types are not used on machines that are 64-bit
- We should never be doing reads/writes of less than 32-bits
- Flags in attribute values are hardcoded
- Need a manpage
- Should handle multiple fonts simulatneously
- Generate an `empty' box character when we have no match?
- Use 'int' in lieu of 'int32' where we can
- Compress some cases in rasops1.c
Note some ideas from Toru Nishimura. 1999-10-07 13:04:10 +04:00			$NetBSD: README,v 1.4 1999/10/07 09:04:10 ad Exp $
Initial import of 'rasops', the new raster operations set for wscons/rcons. 1999-04-13 04:17:57 +04:00
- Change the semantics of rasops_init slightly - 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 1999-08-24 15:07:31 +04:00			This directory contains `rasops', a set of raster operations intended to
