Restore the legacy PowerVR SDK 'BasicTnL' OpenGL ES 1.1 sample
OpenGL ES 1.1 will be removed from the main branch, but this sample can
remain available as basic test of a legacy OpenGL ES 1.1 build.

+ * khronos_int16_t signed 16 bit
+ * khronos_uint16_t unsigned 16 bit

+ * khronos_uint32_t unsigned 32 bit
+ * khronos_int64_t signed 64 bit
+ * khronos_uint64_t unsigned 64 bit
+ * khronos_intptr_t signed same number of bits as a pointer
+ * khronos_uintptr_t unsigned same number of bits as a pointer
+ * khronos_ssize_t signed size
+ * khronos_usize_t unsigned size
+ * khronos_float_t signed 32 bit floating point
+ * khronos_time_ns_t unsigned 64 bit time in nanoseconds
+ * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
+ * nanoseconds
+ * khronos_stime_nanoseconds_t signed time interval in nanoseconds
+ * khronos_boolean_enum_t enumerated boolean type. This should
+ * only be used as a base type when a client API's boolean type is
+ * an enum. Client APIs which use an integer or other type for
+ * booleans cannot use this as the base type for their boolean.
+ *
+ * Tokens defined in khrplatform.h:
+ *
+ * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
+ *
+ * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.

+
+ @section overview Overview
+ *****************************
+
+ PVRShell is a C++ class used to make programming for PowerVR platforms easier and more portable.
+ PVRShell takes care of all API and OS initialisation for the user and handles adapters, devices, screen/windows modes,
+ resolution, buffering, depth-buffer, viewport creation & clearing, etc...
+
+ PVRShell consists of 3 files: PVRShell.cpp, PVRShellOS.cpp and PVRShellAPI.cpp.
+
+ PVRShellOS.cpp and PVRShellAPI.cpp are supplied per platform and contain all the code to initialise the specific
+ API (OpenGL ES, Direct3D Mobile, etc.) and the OS (Windows, Linux, WinCE, etc.).
+ PVRShell.cpp is where the common code resides and it interacts with the user application through an abstraction layer.
+
+ A new application must link to these three files and must create a class that will inherit the PVRShell class.
+ This class will provide five virtual functions to interface with the user.
+
+ The user also needs to register his application class through the NewDemo function:
+
+ @code
+ class MyApplication: public PVRShell
+ {
+ public:
+ virtual bool InitApplication();
+ virtual bool InitView();
+ virtual bool ReleaseView();

+
+ @section interface Interface
+ ******************************
+
+ There are two functions for initialisation, two functions to release allocated resources and a render function:
+
+ InitApplication() will be called by PVRShell once per run, before the graphic context is created.
+ It is used to initialise variables that are not dependant on the rendering context (e.g. external modules, loading user data, etc.).
+ QuitApplication() will be called by PVRShell once per run, just before exiting the program.
+ If the graphic context is lost, QuitApplication() will not be called.
+
+ InitView() will be called by PVRShell upon creation or change in the rendering context.
+ It is used to initialise variables that are dependant on the rendering context (e.g. textures, vertex buffers, etc.).
+ ReleaseView() will be called by PVRShell before changing to a new rendering context or
+ when finalising the application (before calling QuitApplication).
+
+ RenderScene() is the main rendering loop function of the program. This function must return FALSE when the user wants to terminate the application.
+ PVRShell will call this function every frame and will manage relevant OS events.
+
+ There are other PVRShell functions which allow the user to set his/her preferences and get data back from the devices:
+
+ PVRShellSet() and PVRShellGet() are used to pass data to and from PVRShell. PVRShellSet() is recommended to be used
+ in InitApplication() so the user preferences are applied at the API initialisation.
+ There is a definition of these functions per type of data passed or returned. Please check the prefNameBoolEnum, prefNameFloatEnum,
+ prefNameIntEnum, prefNamePtrEnum and prefNameConstPtrEnum enumerations for a full list of the data available.
+
+ This is an example:
+
+ @code
+ bool MyApplication::InitApplication()
+ {
+ PVRShellSet (prefFullScreen, true);
+ }
+
+ bool MyApplication::RenderScene()
+ {
+ int dwCurrentWidth = PVRShellGet (prefHeight);
+ int dwCurrentHeight = PVRShellGet (prefWidth);
+
+ return true;
+ }
+ @endcode
+
+
+ @section helper Helper functions
+ *************************************
+
+ The user input is abstracted with the PVRShellIsKeyPressed() function. It will not work in all devices, but we have tried to map the most
+ relevant keys when possible. See PVRShellKeyName enumeration for the list of keys supported. This function will return true or false depending on
+ the specified key being pressed.
+
+ There are a few other helper functions supplied by PVRShell as well. These functions allow you to read the timer, to output debug information and to
+ save a screen-shot of the current frame:
+
+ PVRShellGetTime() returns time in milliseconds.
+
+ PVRShellOutputDebug() will write a debug string (same format as printf) to the platform debug output.
+
+ PVRShellScreenCaptureBuffer() and PVRShellWriteBMPFile() will be used to save the current frame as a BMP file. PVRShellScreenCaptureBuffer()
+ receives a pointer to an area of memory containing the screen buffer. The memory should be freed with free() when not needed any longer.
+
+ Example of screenshot:
+
+ @code
+ bool MyApplication::RenderScene()
+ {
+ [...]
+
+ unsigned char *pLines;
+
+ PVRShellScreenCaptureBuffer(PVRShellGet (prefWidth), PVRShellGet (prefHeight), &pLines);
+
+ PVRShellScreenSave("myfile", pLines, NULL);
+
+ free (pLines);
+
+ return true;
+ }
+ @endcode
+
+
+ @section cmd Command-line
+ *************************************
+
+ Across all platforms, PVRShell takes a set of command-line arguments which allow things like the position and size of the demo
+ to be controlled. The list below shows these options.
+
+ \b -width=N Sets the horizontal viewport width to N.
+
+ \b -height=N Sets the vertical viewport height to N.
+
+ \b -posx=N Sets the x coordinate of the viewport.
+
+ \b -posy=N Sets the y coordinate of the viewport.
+
+ \b -aasamples=N Sets the number of samples to use for full screen anti-aliasing. e.g 0, 2, 4, 8
+
+ \b -fullscreen=N Enable/Disable fullscreen mode. N can be: 0=Windowed 1=Fullscreen.
+
+ \b -qat=N Quits after N seconds.
+
+ \b -qaf=N Quits after N frames.
+
+ \b -powersaving=N Where available enable/disable power saving. N can be: 0=Disable power saving 1=Enable power saving.
+
+ \b -vsync=N Where available modify the apps vsync parameters.
+
+ \b -version Output the SDK version to the debug output.
+
+ \b -info Output setup information (e.g. window width) to the debug output.
+
+ \b -rotatekeys=N Sets the orientation of the keyboard input. N can be: 0-3, 0 is no rotation.
+
+ \b -c=N Save a single screenshot or a range. e.g. -c=1-10, -c=14.
+
+ \b -priority=N EGL only. Sets the priority of the EGL context.
+
+ \b -colourbpp=N EGL only. When choosing an EGL config N will be used as the value for EGL_BUFFER_SIZE.
+
+ \b -depthbpp=N EGL only. When choosing an EGL config N will be used as the value for EGL_DEPTH_SIZE.
+
+ \b -config=N EGL only. Force the shell to use the EGL config with ID N.
+
+ \b -forceframetime=N Alter the behaviour of PVRShellGetTime so its returned value is frame based (N denotes how many ms a frame should pretend to last). You can also use the shortened version of -fft and the command can be used without N being defined, e.g. just -forceframetime. This option is provided to aid in debugging time-based applications.
+
+ Example:
+ @code
+ Demo -width=160 -height=120 -qaf=300
