Why is API level 10 the minimum required?
================================================================================
API level 10 is required because SDL requires some functionality for running not
available on older devices and some for building which is not in older NDK/SDKs.
Support for native OpenGL ES and ES2 applications was introduced in the NDK for
API level 4 and 8. EGL was made a stable API in the NDK for API level 9, which
has since then been obsoleted, with the recommendation to developers to bump the
required API level to 10.
As of this writing, according to http://developer.android.com/about/dashboards/index.html
about 90% of the Android devices accessing Google Play support API level 10 or
higher (March 2013).
================================================================================
A note regarding the use of the "dirty rectangles" rendering technique
================================================================================
If your app uses a variation of the "dirty rectangles" rendering technique,
where you only update a portion of the screen on each frame, you may notice a
variety of visual glitches on Android, that are not present on other platforms.
This is caused by SDL's use of EGL as the support system to handle OpenGL ES/ES2
contexts, in particular the use of the eglSwapBuffers function. As stated in the
documentation for the function "The contents of ancillary buffers are always
undefined after calling eglSwapBuffers".
Setting the EGL_SWAP_BEHAVIOR attribute of the surface to EGL_BUFFER_PRESERVED
is not possible for SDL as it requires EGL 1.4, available only on the API level
17+, so the only workaround available on this platform is to redraw the entire
screen each frame.

Simple DirectMedia Layer for Nintendo DS
================================================================================
-Requirements-
* The devkitpro SDK available at http://devkitpro.org.
Read the information at http://devkitpro.org/wiki/Getting_Started/devkitARM
The necessary packages are devkitARM, libnds, libfat and default arm7.
* Optionally, use a DS emulator, such as desmume (http://desmume.org/)
to program and debug.
-Building SDL-
After setting the devkitpro environment, cd into your SDL directory and type:
make -f Makefile.ds
This will compile and install the library and headers into the
devkitpro's portlibs directory (../portlibs/arm/lib/ and
../portlibs/arm/include/). Additionally it will compile several tests
that you can run either on the DS or with desmume. For instance:
desmume --cflash-path=test/ test/nds-test-progs/testsprite2/testsprite2.nds
desmume --cflash-path=test/ test/nds-test-progs/testspriteminimal/testspriteminimal.nds
desmume --cflash-path=test/ test/nds-test-progs/testscale/testscale.nds
desmume test/nds-test-progs/general/general.nds
-Notes-
* The renderer code is based on the gl like engine. It's not using the sprite engine.
* The hardware renderer is using the parts of the libgl2d abstraction library that can be found at:
http://rel.phatcode.net/junk.php?id=117
Used with the author's permission.
* The port is very basic and incomplete:
- SDL currently has to be compiled for either framebuffer mode or renderer mode.
See USE_HW_RENDERER in Makefile.ds.
- some optional renderer functions are not implemented.
- no sound
-Limitations-
* in hardware renderer mode, don't load too many textures. The internal format is
2 bytes per pixel. And there is only 256KB reserved for the textures. For instance,
testscale won't display sample.bmp, unless it's resized to a smaller picture.
* the screen size is 256 x 384. Anything else won't work.
* there is no 8 bits/pixel mode because SDL 2.0 doesn't support palettes.
-Joystick mapping-
The Joystick presented to SDL has 2 axes and 8 buttons
KEY | Code
A | 0
B | 1
X | 2
Y | 3
L | 4
R | 5
select | 6
start | 7
Left-right is axe 0.
Up-down is axe 1.
-Mouse mapping-
todo
-Examples-
Due to memory limitations, to be able to successfully run the testscale example, sample.bmp must be resized to 256x105.

SDL 2.0 with open pandora console support ( http://openpandora.org/ )
=====================================================================
- A pandora specific video driver was writed to allow SDL 2.0 with OpenGL ES
- A pandora specific video driver was written to allow SDL 2.0 with OpenGL ES
support to work on the pandora under the framebuffer. This driver do not have
input support for now, so if you use it you will have to add your own control code.
The video driver name is "pandora" so if you have problem running it from

The linux touch system is currently based off event streams, and proc/bus/devices. The active user must be given permissions to read /dev/input/TOUCHDEVICE, where TOUCHDEVICE is the event stream for your device. Currently only Wacom tablets are supported. If you have an unsupported tablet contact me at jim.tla+sdl_touch@gmail.com and I will help you get support for it.
Mac:
The Mac and Iphone API's are pretty. If your touch device supports them then you'll be fine. If it doesn't, then there isn't much we can do.

Functions
===========================================================================
SDL provides the ability to access the underlying Touch and Finger structures.
SDL provides the ability to access the underlying Finger structures.
These structures should _never_ be modified.
The following functions are included from SDL_Touch.h
The following functions are included from SDL_touch.h
To get a SDL_Touch device call SDL_GetTouch(touchId).
This returns an SDL_Touch*.
IMPORTANT: If the touch has been removed, or there is no touch with the given ID, SDL_GetTouch will return null. Be sure to check for this!
To get a SDL_TouchID call SDL_GetTouchDevice(index).
This returns a SDL_TouchID.
IMPORTANT: If the touch has been removed, or there is no touch with the given ID, SDL_GetTouchID will return 0. Be sure to check for this!
An SDL_Touch has the following fields:
>xres,yres,pressures:
The resolution at which x,y, and pressure values are reported. Currently these will always be equal to 2^15, but this may not always be the case.
The number of touch devices can be queried with SDL_GetNumTouchDevices().
>pressure_max, pressure_min, x_max, x_min, y_max, y_min
Which give, respectively, the maximum and minumum values that the touch digitizer can return for pressure, x coordiniate, and y coordinate AS REPORTED BY THE OPERATING SYSTEM.
On Mac/iPhone systems _max will always be 0, and _min will always be 1.
A SDL_Touch may be used to get pointers to SDL_Finger.
>native_xres,native_yres,native_pressureres:
The native resolution of the touch device AS REPORTED BY THE OPERATING SYSTEM.
On Mac/iPhone systems these will always be 1.
SDL_GetNumTouchFingers(touchID) may be used to get the number of fingers currently down on the device.
>num_fingers:
The number of fingers currently down on the device.
The most common reason to access SDL_Finger is to query the fingers outside the event. In most cases accessing the fingers is using the event. This would be accomplished by code like the following:
>fingers:
An array of pointers to the fingers which are on the device.
The most common reason to access a touch device is to normalize inputs. This would be accomplished by code like the following:
SDL_Touch* inTouch = SDL_GetTouch(event.tfinger.touchId);
if(inTouch == NULL) continue; //The touch has been removed
float x = ((float)event.tfinger.x)/inTouch->xres;
float y = ((float)event.tfinger.y)/inTouch->yres;
float x = event.tfinger.x;
float y = event.tfinger.y;
To get an SDL_Finger, call SDL_GetFinger(touch,fingerId), where touch is a pointer to an SDL_Touch device, and fingerId is the id of the requested finger.
This returns an SDL_Finger*, or null if the finger does not exist, or has been removed.
An SDL_Finger is guaranteed to be persistent for the duration of a touch, but it will be de-allocated as soon as the finger is removed. This occurs when the SDL_FINGERUP event is _added_ to the event queue, and thus _before_ the FINGERUP event is polled.
As a result, be very careful to check for null return values.

The previous coordinates of the touch.
>pressure:
The pressure of the touch.

The theory here is that by default we forcibly inline what we can, and your
app will use the inline version by default. However we expose a non-inline
version too, so the symbol is always available in the library even if your app
bypassed the inline version. The SDL_*_inline versions aren't guaranteed to
exist, so never call them directly; use SDL_* instead, and trust the system
to give you the right thing.
The benefit here is that you can dlsym() these functions, which you
couldn't if you had macros, you can link against a foreign build of SDL
even if you configured differently, and you can drop the unconfigured SDL
headers into a project without #defining HAVE_MALLOC (etc) and still link.
