Bruce Evans 38862a5553 Stop using a saveunder method for mouse cursor drawing in the vga
direct mode renderer.  I thought that reads were not much slower than
writes, so that the method only tripled the time for the whole function,
but I recently measured that video memory reads can be up to 53 times
slower than writes in tighter loops than here.  Loop overheap here
reduces the multiplier to only 16-20 on Haswell.

Start cleaning up and fixing larger bugs in this function.  Only replace
the 22-line removal loop by a 3-line one for now, since adjusting the
old loop would have required many palette calculations which are better
done in the DRAW_PIXEL() macro.  This also fixes missing support for
depth 24, but only for removal.

Removal is currently sloppy at the right bottom corner.  It sometimes
leaks border color into the text window.  This is soon cleaned up by the
caller.  The planar renderer has complications to clip at the corner.

FreeBSD Source:

This is the top level of the FreeBSD source directory. This file was last revised on: FreeBSD

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).

The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.

The buildkernel and installkernel targets build and install the kernel and the modules (see below). Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags.

Building a kernel is a somewhat more involved process. See build(7), config(8), and http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.

Note: If you want to build and install the kernel with the buildkernel and installkernel targets, you might need to build world before. More information is available in the handbook.

The kernel configuration files reside in the sys/<arch>/conf sub-directory. GENERIC is the default configuration used in release builds. NOTES contains entries and documentation for all possible devices, not just those commonly used.
