The previous commit also fixed the coordinates passed to the mouse removal renderer. The coordinates were rounded down to a character boundary, and thus essentially unusable. The renderer had to keep track of the previous position, or clear a larger area. The latter is only safe in the border, which is all that needs special handling anyway. I think no renderer depends on the bug. They have the following handling: - gfb sparc64: this seems to assume non-rounded coordinates - gfb other: does nothing (seems to be missing border handling) - vga text: does nothing (doesn't need border handling) - vga planar: clears extras in the border, with some bugs. The fixes will use the precise coordinates to optimize. - vga direct: clears at the previous position with no check that it is active, and clears everything. Checking finds this bug. - others: are there any?

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.
