defaults have been specified. The reason being, testers will be running old

to continually reset 'tia.core' every time they run a new build. Besides,
the point is for the new core to be the default, so we may as well enforce that

Some formatting cleanups in various classes.

Made getPixel method from each of the TIA objects inline, since they're called

Introduced Cartridge::initializeRAM() method, to eliminate duplicate

Added shortcut key to toggle TV scanline jittering, and have it default

Introduce namespace to class MD5, so the method call is now MD5::hash()
instead of simply MD5().
Added C++11 '= delete' constructors to most classes, to more clearly

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

all conditions.

a snapshot of either the FrameBuffer or an FBSurface, and adds

There are still some issues, though. First, SDL2.0.3 has to compiled

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 ...

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

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 ...

Added fallback to FBSurface::drawSurface() in case certain ports don't
want to implement it natively.

surfaces or TIA surfaces.

rectangles. Now that the underlying rendering is hardware accelerated,
this API more closely matches what is actually occurring. As well, it
makes things easier comprehend: 'src' rect is the actual surface data,
and 'dst' rect is its final output onscreen (scaling, etc being applied).

FBSurface::drawSurface() is essentially the same thing, and will
probably be removed.

to Xcode 5.

functionality of FBSurfaceUI into FBSurface directly, since there was
absolutely no need of the SDL-specific code to know about underlying
FrameBuffer-specific stuff. This makes a clear separation between
SDL and the core code, making porting easier in the future. As a
result, renamed FBSurfaceUI as FBSurfaceSDL2.
Eventually, FBSurfaceTIA will disappear completely, being integrated
into FBSurface and FBSurfaceSDL2. Again, the logic for drawing the
TIA and using Blargg, etc has absolutely no place in SDL-specific
areas of the code.
When this conversion is complete, I see FrameBufferSDL2 and FBSurfaceSDL2
as being thin wrappers around SDL-specific functions that simply push
pixel data to the video system.

moving thing out of the xxxSDL classes that don't really have anything
to do with SDL. This will also make it easier to port Stella to other
graphical toolkits.

Rearranged some of the desktop size code, to be more consistent with the
new API.
Beginning to remove the old assumptions that a smaller screen than 640x480
could be used. In the 4.0 release, the smallest (internal) screen
supported will actually be 640x480, and if the real desktop can't display
it, then it will be scaled down. This is one of the nice benefits of
killing pure software rendering support, and letting the hardware just
draw the screen as it likes.

There are changes all over the FrameBuffer classes. Still TODO is
TIA resizing in windowed mode, and all fullscreen modes. The infrastructure
is close to completion, and it should be pretty easy to get the framebuffer
stuff done in the next week or so.

SDL Window events are now sent to the EventHandler core. For now, only
the window expose event is handled (redraws window if it's been hidden).

recommended) or Direct3D/OpenGL in Windows.
The app icon is now loaded in Windows.
Cleaned up the VideoDialog UI, removing references to double-buffering

now start with 'tia.'. This includes most of the old options that
started with 'gl_'.
Changed the names of all tv-effects options from starting with 'tv_'
to 'tv.', to match the name changes elsewhere.
Some work on the documentation to reflect the latest changes.

then. Expect breakage on a regular basis over the next month or so.

of a larger reorganization of the codebase, to completely remove
SDL-specific code from src/emucore, and make it easier to port to SDL2.

easier, since it won't be touching any of the core emulation code in src/emucore.
Next TODO is something similar for EventHandler (which uses SDL heavily and is
too tied to a core class).

code will be removed, and replaced by SDL2-specific hardware-accelerated
code.
Cleaned up (mostly) the API of FrameBuffer vs FrameBufferSDL2. Since the
FrameBuffer class is an emucore object, it should have no knowledge of SDL,
or any particular rendering toolkit for that matter (just in case we want
to move to SDL3 eventually :) ).
At this point, all checks for OpenGL have been removed, so if you don't
have it on your system, Stella will fail to compile and/or run.

Once a frame has started, it means a new frame should be added. This
fixes a bug in the debugger UI whereby the frame count showed the previous
value, since sometimes you could enter the debugger (with a cond BP)
before the end of the frame was technically reached.

bases into a Common::Base class. Previously, this functionality was
spread across several classes, and used different approaches to formatting.
While the code still mixes C++ streams and C-style sprintf's, at least
it will now be easier to modify it all in one place.
Related to the above, added ability to use upper or lower case
characters for HEX output in the debugger. This is toggled by the
new debugger prompt command 'uhex', which is also tied to a new
commandline argument, 'dbg.uhex'.

All DataGridWidgets (ie, most of the inputs in the debugger) have more
strict input filtering, allowing to use $,#,\ specifiers for different
bases, as well as restricting input based on the specifier used (ie, if
you've entered a '\', only '0' and '1' are allowed, etc).

will be used, but at least we can improve it a little).
Eliminated the 'alignment' dimension in the various TIATables masks,
reducing the size of the arrays by a factor of 4. I could never
figure out what alignment meant, until I looked at old TIA code in
the repo. It seems that originally, there was an optimization
in the code to fill the array on 32-bit boundaries, instead of the
current 8-bit boundary. As a result, the masks had to be defined
as 32-bits, or 4 groups of 8-bits. Ah, that's where the 'alignment'
comes from.
Related to this, the colors and pointers in the TIA class are now
8-bit as well. Essentially, the TIA class has been doing extra
work to align everything to 32-bit and never actually using the
results. And it's been this way for 4+ years.
Older state files will no longer work, so the version # has been
bumped.

The format for displaying disassembler GFX/PGFX (binary or hex) is now
obeyed in the disassembly file output as well.
Changed various comments/enums/etc referring to 'preliminary' code to

Fixed bug after pressing Enter/Return in EditTextWidgets; it was exiting

Some cleanup of the various enum's in the UI classes.
Fixed issues with ordering when adding dialog boxes; this fixes a
bug when adding a dialog from another dialogs ::loadConfig(), in
which case the first one is placed below the second and can't be
seen (mostly applies to MessageBoxes).
Fixed bug in handling OSystem::setBaseDir(); if the directory didn't
exist, then the newly created one wouldn't have a slash appended at the
end. This causes all further (sub)directories to be created/named
incorrectly.

where commands/shortcut keys typed in the debugger would be interpreted
as actual CompuMate input.
For now, in-debugger key processing is completely disabled in such a

CM RIOT area, and have it send its data directly to the CM handler.
