		102	=head1 OPENCL 1.1 VS. OPENCL 1.2
		103
		104	This module supports both OpenCL version 1.1 and 1.2, although the OpenCL
		105	1.2 interface hasn't been tested much for lack of availability of an
		106	actual implementation.
		107
		108	Every function or method in this manual page that interfaces to a
		109	particular OpenCL function has a link to the its C manual page.
		110
		111	If the link contains a F<1.1>, then this function is an OpenCL 1.1
		112	function. Most but not all also exist in OpenCL 1.2, and this module
		113	tries to emulate the missing ones for you, when told to do so at
		114	compiletime. You cna check whether a function was removed in OpenCL 1.2 by
		115	replacing the F<1.1> component in the URL by F<1.2>.
		116
		117	If the link contains a F<1.2>, then this is a OpenCL 1.2-only
		118	function. Even if the module was compiled with OpenCL 1.2 header files
		119	and has an 1.2 OpenCL library, calling such a function on a platform that
		120	doesn't implement 1.2 causes undefined behaviour, usually a crash (But
		121	this is not guaranteed).
		122
		123	You can find out whether this module was compiled to prefer 1.1
		124	functionality by ooking at C<OpenCL::PREFER_1_1> - if it is true, then
		125	1.1 functions generally are implemented using 1.1 OpenCL functions. If it
		126	is false, then 1.1 functions missing from 1.2 are emulated by calling 1.2
		127	fucntions.
		128
		129	This is a somewhat sorry state of affairs, but the Khronos group choose to
		130	make every release of OpenCL source and binary incompatible with previous
		131	releases.

		342	=head2 How to modify the previous example to not rely on GL sharing.
		343
		344	For those poor souls with only a sucky CPU OpenCL implementation, you
		345	currently have to read the image into some perl scalar, and then modify a
		346	texture or use glDrawPixels or so).
		347
		348	First, when you don't need gl sharing, you can create the context much simpler:
		349
		350	$ctx = $platform->context (undef, [$dev])
		351
		352	To use a texture, you would modify the above example by creating an
		353	OpenCL::Image manually instead of deriving it from a texture:
		354
		355	my $tex = $ctx->image2d (OpenCL::MEM_WRITE_ONLY, OpenCL::RGBA, OpenCL::UNORM_INT8, $S, $S);
		356
		357	And in the draw loop, intead of acquire_gl_objects/release_gl_objects, you
		358	would read the image2d after the kernel has written it:
		359
		360	$queue->read_image ($tex, 0, 0, 0, 0, $S, $S, 1, 0, 0, my $data);
		361
		362	And then you would upload the pixel data to the texture (or use glDrawPixels):
		363
		364	glTexSubImage2D_s GL_TEXTURE_2D, 0, 0, 0, $S, $S, GL_RGBA, GL_UNSIGNED_BYTE, $data;
		365
		366	The fully modified example can be found at
		367	L<http://cvs.schmorp.de/OpenCL/examples/juliaflight-nosharing>.
		368
		369	=head2 Julia sets look soooo 80ies.
		370
		371	Then colour them differently, e.g. using orbit traps! Replace the loop and
		372	colour calculation from the previous examples by this:
		373
		374	float2 dm = (float2)(1.f, 1.f);
		375
		376	for (int i = 0; i < 25; ++i)
		377	{
		378	z = (float2)(z.x * z.x - z.y * z.y, 2.f * z.x * z.y) + c;
		379	dm = fmin (dm, (float2)(fabs (dot (z, z) - 1.f), fabs (z.x - 1.f)));
		380	}
		381
		382	float3 colour = (float3)(dm.x * dm.y, dm.x * dm.y, dm.x);
		383
		384	Also try C<-10.f> instead of C<-1.f>.

		1534
		1535	OpenCL allows you to map buffers and images to host memory (read: perl
		1536	scalars). This is done much like reading or copying a buffer, by enqueuing
		1537	a map or unmap operation on the command queue.
		1538
		1539	The map operations return an C<OpenCL::Mapped> object - see L<THE
		1540	OpenCL::Mapped CLASS> section for details on what to do with these
		1541	objects.
		1542
		1543	The object will be unmapped automatically when the mapped object is
		1544	destroyed (you can use a barrier to make sure the unmap has finished,
		1545	before using the buffer in a kernel), but you can also enqueue an unmap
		1546	operation manually.

		2014	Sets the arguments of a kernel. Since OpenCL 1.1 doesn't have a generic

		2018

		2025	i int

		2200	=head2 THE OpenCL::Mapped CLASS
		2201
		2202	This class represents objects mapped into host memory. They are
		2203	represented by a blessed string scalar. The string data is the mapped
		2204	memory area, that is, if you read or write it, then the mapped object is
		2205	accessed directly.
		2206
		2207	You must only ever use operations that modify the string in-place - for
		2208	example, a C<substr> that doesn't change the length, or maybe a regex that
		2209	doesn't change the length. Any other operation might cause the data to be
		2210	copied.
		2211
		2212	When the object is destroyed it will enqueue an implicit unmap operation
		2213	on the queue that was used to create it.
		2214
		2215	Keep in mind that you I<need> to unmap (or destroy) mapped objects before
		2216	OpenCL sees the changes, even if some implementations don't need this
		2217	sometimes.
		2218
		2219	Example, replace the first two floats in the mapped buffer by 1 and 2.
		2220
		2221	my $mapped = $queue->map_buffer ($buf, ...
		2222	$mapped->event->wait; # make sure it's there
		2223
		2224	# now replace first 8 bytes by new data, which is exactly 8 bytes long
		2225	# we blindly assume device endianness to equal host endianness
		2226	# (and of course, we assume iee 754 single precision floats :)
		2227	substr $$mapped, 0, 8, pack "f*", 1, 2;
		2228
		2229	=over 4
		2230
		2231	=item $ev = $mapped->unmap ($wait_events...)
		2232
		2233	Unmaps the mapped memory object, using the queue originally used to create
		2234	it, quite similarly to C<< $queue->unmap ($mapped, ...) >>.
		2235
		2236	=item $bool = $mapped->mapped
		2237
		2238	Returns whether the object is still mapped - true before an C<unmap> is
		2239	enqueued, false afterwards.
		2240
		2241	=item $ev = $mapped->event
		2242
		2243	Return the event object associated with the mapped object. Initially, this
		2244	will be the event object created when mapping the object, and after an
		2245	unmap, this will be the event object that the unmap operation created.
		2246
		2247	=item $mapped->wait
		2248
		2249	Same as C<< $mapped->event->wait >> - makes sure no operations on this
		2250	mapped object are outstanding.

		2258	Returns the raw memory address of the mapped area.
		2259
		2260	=item $mapped->set ($offset, $data)
		2261
		2262	Replaces the data at the given C<$offset> in the memory area by the new
		2263	C<$data>. This method is safer than direct manipulation of C<$mapped>
		2264	because it does bounds-checking, but also slower.

		2267
		2268	Returns (without copying) a scalar representing the data at the given
