2be7c7c88d Always print the mouse cursor, even if coordinates haven't changed. 
This makes sure that the cursor is always visible, even if the program
has written text to the screen (only valid for non-P/M mouse callbacks).

4065cb1983 Harmonized interface between mouse drivers and callbacks. 
The Apple2 doesn't have sprites so the Apple2 mouse callbacks place a special character on the text screen to indicate the mouse position. In order to support the necessary character removing and redrawing the Apple2 mouse driver called the Apple2 mouse callbacks in an "unusual way". So far so (sort of) good.

However the upcoming Atari mouse driver aims to support both "sprite-type" mouse callbacks as well as "text-char-type" mouse callbacks. Therefore the interface between mouse drivers and callbacks needs to be extended to allow the mouse callbacks to hide their different types from the mouse driver.

The nature of this change can be seen best by looking at the Apple2 file modifications. The CBM drivers and callbacks (at least the current ones) don't benefit from this change.

The CBM510 runs programs in a non-system memory bank. It has its own zero page. Some things are copied from the system zero page; but, the cursor flags weren't copied. So, the cursor always blinked. That bug sometimes left cursor ghosts (reversed spaces) at the end of lines.

e63bf1cde1 Used a library-reference method to calibrate lightpen drivers. 
The mouse reference is a pointer.  If it's NULL, the driver uses a default.  If it's non-NULL, then it points to a function that the driver can call.  That function will adjust the driver's calibration value.  It could ask the user to adjust the pen; or, it could read a file that holds a value from a previous calibration.

Application writers can choose how it's done: a function that's provided by the library, a custom function, or nothing.

Occasionally dynamically drivers suffer from not being to refer to
content in the C library. Therefore I added a mechanism to allow
a C library for a certian target to define a symbol that will be
handed over to dynamic drivers for that target. Then the drivers
can use their refernce to that symbol to access content in the C
library.

7024e2789d Explicitly set search paths for libraries build. 
The libraries build is prepared to work with binaries not part of the current
working tree. But in this case the default search path surely points to some
other working tree. Even the binaries in this working tree might have been
compiled with non-standard builtin search paths.

Anyway when building the libraries we want always to use the headers from
the current working tree. Therefore we want to set them explicitly. Instead
of setting all in all five paths on the command lines of ca65, cc65 and ld65 I
opted to just set the single environment variable.

55f9e6ac25 Added 'sim6502' and 'sim65C02' targets. 
The targets allow to run cc65 programs in the sim65 exection
einvironment. As there are no "real" i/o facilities there's no
need for header files. Paravirtualized entry points are mapped
to $FFF0 ff. There's a large cc65 progam area from $0200-$FFEF.

The binary format includes a one-byte header indicating the required
execution environment: The value 0 means 6502 and the value 1
means 65C02. The load adress for the binary is fixed to $0200.

Note: Running sim65C02 programs currently doesn't work bcause
sim65 doesn't actually implement 65C02 opcodes.

00bb0f9704 Hack: Changed TARGET order to have apple2enh.lib available for convert.system. 
There's a quite special case of a targetutil for the TARGET geos-apple having to be
built as TARGET apple2enh binary. We can't just add a dependency to ../lib/apple2enhlib
because the TARGETs are built in individual make instances (because of vpath).

Doing that the "right way" would be _very_ complicated and would turn the Makefiles way
less readable. Therefore I decided to solve that by just reordering the TARGETs. Surely
this won't work if i.e. 'make geos-apple' is entered on a clean system. But still I consider
it appropriate.

I ordered the TARGETs btw so that they are more in an alphabetical order...
