the RAM is always mapped into the same place in ROM, the ram grid
now shows addresses with the correct read port address, and
ram labels are properly accessed. In cases where the RAM is hidden
from the 6507 or not mapped into the same place at the same time,
the addresses show actual real addresses of the RAM from the POV of
the cart itself (ie, RAM location zero is labeled 0, not as $1xxx).
This is necessary since quiescent RAM doesn't actually have a 6507
address. Also, labels are disabled in this case.
Fixed bug with incorrect offsets when reading cart RAM labels;
it seems to be a copy/paste issue, since all such methods were
written as if the cart was SaraChip-based.

fix issues in Ubuntu Unity, and caused CPU usage to spike to 100% in
all other tested platforms. So for now, I'm putting it back to low
CPU usage for all other platforms (Linux w/o Unity, OSX, Windows, etc),
and treating this as a Unity bug (which isn't unheard of).

This code was originally there for software mode, where it was very
expensive to update pixels, so it was done as little as possible.
However, it was also a bit of a hack, and sometimes interfered with
double-buffered hardware rendering. So now showing the various UI's
will burn slightly more CPU, but will be guaranteed to work under
all conditions.

snapshot of the TIA image, including partial rendering (if applicable)
and scanline indicator. Previously it only saved the TIA image, which
basically made it useless from the debugger POV.

32 and 64-bit Universal Binaries, and there is now a development
and deployment target. Finally, the build DMG script now
works again.

having to know about TIA, Properties, etc. Basically, it now saves
a snapshot of either the FrameBuffer or an FBSurface, and adds
text comments passed into it. The contents of the surface and comments
are no longer calculated (or known) by the PNG code.
This is in preparation for saving FBSurface from anywhere, which will
help in the debugger for taking snapshots.

This sometimes results in a window resize being visible, but better that than
an outright crash. This issue has been reported to the SDL mailing list,
so this fix may be backed out in the future.

and contains only one Objective-C warning (more research required). There
are also some fixes for minor warnings.
There are still some issues, though. First, SDL2.0.3 has to compiled
manually, as the public binaries don't work (this is documented and
a bug reported on the SDL mailing list). Second, fullscreen->window
transition is causing a crash, which I still need to track down.

for a long time. Changed to unsigned int everywhere, and removed
functions that I will never use (the class originally came from
ScummVM).

to SDL mod.
Added a hack/fix for Alt-key combos being printed in the debugger
prompt (ie, when stepping though a frame with Alt-f, the 'f' character
was shown in the prompt). This will be fixed when PromptWidget
becomes an EditableWidget (not for the 4.0 release).

cart bankswitch type, allowing much more information to be shown than
you'd see in the normal RAM area.

scroll events from SDL1 to SDL2.
Bumped version #. It looks like the current code is now bug-fixed
and equivalent to release 3.9.3. Now on to committing some backlogged
patches and adding new functionality.

which I though a just a one or two-liner equivalent to glReadPixels.
Turns out that SDL2 doesn't return 24-bit RGB data (only 16 or 32-bit),
so the PNGLibrary had to massage the data. In the process, converted
the PNG saving functions to actually use PNG library functions, which
greatly simplified converting packing from 32 -> 24-bit. Historically,
the PNG save functions were written before libpng was a requirement,
so they were hand-rolled. Once libpng was integrated into the codebase,
it didn't make much sense to not use it anymore.
So an expected two-line code fix became this commit ...

PromptWidget class to use EditableWidget will probably happen after
release 4.0).
All text input now seems to be working as in Stella 3.9.3.
git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@2915 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
(specifically, DataGridWidget and RomListWidget are now working).
More work is required for PromptWidget, since it was created before
EditableWidget existed, and hence duplicates a lot of that classes code.

the old way mixed both single-key events and Unicode input into one
method, and the new way separates them (using a new handleText method).
Currently it seems to be working fine in the ROM launcher (yay!, I
can now quickly jump to ROMs by name again). There are still some
issues in the debugger, which I'll work on next.

Technically, the magic numbers are still being used, but now they're
no longer exposed outside the System class by default.

resolved "access" initialisaation. Bizarre stuff and a bit of handwaving magic, but at least it runs the test ROM as a "DASH" version now.

removed 'myCurrentBank' -- this has no meaning in this scheme.
Adjusted load() to switch in each bank as it is loaded
removed comment/questions to SA and replaced per advice.
added a few TODO comments.
reformatted some of the comments back, as per discussion

constants for bit masking added

and (simulated) fullscreen mode.
Fullscreen mode is now simulated in that it creates a window that matches
what would appear in fullscreen. The next thing to do is actually have
the backend create this fullscreen mode correctly.
Changed 'gl_fsscale' to 'tia.fsfill' to more properly indicate what the
option does.

Changed pointers to references in c'tor calls, making things a little safer.
Removed FBSurfaceTIA, since it was tied too closely to SDL itself. Added a
class called TIASurface that is functionally very similar, but is more generic
and accessible by the FrameBuffer directly. Eventually, this class will take
responsibility for all things related to rendering the TIA image (Blargg TV
effects, phosphor mode, etc).
TIA rendering is currently borked; fixes will follow ...

want to implement it natively.
