TODO: some convenience methods maybe?

TODO: get/set -> get/put with offset/coordinates at end?
        - OpenCL 1.2 is now effectively feature complete (but hardly tested).
        - implement these 1.2 functions:
          $device->sub_devices,
          $ctx->program_with_built_in_kernels,
          $ctx->link_program,
          $program->compile,
          $kernel->arg_info (and all 5 accessor methods),
          $queue->migrate_mem_objects.
        - implement OpenCL::context.
        - implement $memory->destructor_callback.
        - remove $kernel->set_image[23]d.
        - add most enum and bitfield symbols to the manpage, for quick reference.
        - default all constants to -1, instead of having them missing.
        - try hard to get d3d definitions, when/if possible.
        - add numerical limits and floating point constants from cl_platform.h.
        - unify C types for accessors, for further code size decrease.

        - OpenCL 1.1 is now effectively feature complete.
        - work around a bug in the nvidia implementation, where build fails with
          INVALID_BINARY if the compiler runs succesfully but ptxas fails.
        - explicitly check for 0 size dimensions in nd_range_kernel, as nvidia
          crashes (and OpenCL probably allows this behaviour).
        - actually report clSetKernelArg errors in ("OpenCL::Kernel::setf.
        - setf properly can now properly set local arguments ('z').
        - using undef to pass null memory buffers now works in set_xxx.
        - release_gl_texture was missing.
        - fix/improve/balance gl sharing example.
        - added non-opengl sharing opengl example.
        - fixed some documentation links.
        - fixed a bug where enqueue operations with optional parameters at the
          end not specified would crash.
        - implemented clEnqueueMapBuffer/Image/UnmapMemObject, and a "mapped object"
          abstraction.
        - both context_from_type methods now properly pass the notify callback.
        - $platform->context now properly passes CL_CONTEXT_PLATFORM again.
        - implement clCreateProgramWithBinary.
        - speed up object constructions by not looking up stashes.
        - use libebc for fine-tuning.
        - reduce codesize considerably by disabling inlining on some functions.
        - speed up many method calls on objects with no subclasses.

0.98 Sat Apr 28 15:31:46 CEST 2012
        - INCOMPATIBLE CHANGE: $prog->build now wants an array of devices, or undef.
        - INCOMPATIBLE CHANGE: $queue->enqueue_xxx methods have been renamed to just
          $queue->xxx, the enqueue_ prefix has been deprecated.
        - INCOMPATIBLE CHANGE: use ->set_image to set kernel args, ->image[23]d have
          been deprecated.
        - new $kernel->setf function to set kernel arguments in one go.
        - (optional, automatic) anyevent integration.
        - implement an event queue, use Async::Interrupt for communication.
        - implement context notification callbacks (untested).
        - provide a default context notification function that prints to stderr.
        - implement event callback notifications.
        - implement build program notifications.
        - implement an asynchronous program build function.
        - $ctx->build_program now distinguishes between wrong build invocations
          and build failures.

0.97 Tue Apr 24 16:56:21 CEST 2012
        - created $ctx->build_program utility function.
        - enqueue_acquire/release_gl_objects did not return an event object.
        - OpenCL::errno did not return the correct value.
        - allow undef values in event wait lists, for convenience.
        - implement $program->kernels_in_program.
        - add opencl 1.2 constants.
        - implement $ctx->image, $ctx->gl_texture, $platform->unload_compiler,
          $queue->enqueue_fill_buffer/image, all untested (opencl 1.2).
        - port image2d and image3d to the opencl 1.2 API.
        - port enqueue_marker/barrier to the opencl 1.2 API, and croak
          if the user requests something that 1.1 cannot do when compiled
          against 1.1. This slightly changes the API for enqueue_barrier,
          which now checks the context it is called in.
        - add ->format accessor for CL_IMAGHE_FORMAT.
        - $object->id function to access internal object id.

0.96 Fri Apr 20 22:23:58 CEST 2012

          (gl_buffer, gl_texture[23]d, gl_renderbuffer).
        - support some cl_khr_gl_sharing extensions.
        - add some extension constants (cl_gl.h cl_ext.h, cl_d3d10.h).
        - auto-generate error codes (and include gl+d3d extensions).

0.92 Mon Apr 16 08:39:21 CEST 2012
        - work around some bugs in amd's opencl implementation (INVALID_HOST_PTR
          when value deosn't matter).

0.91 Sun Dec 11 00:05:02 CET 2011

          132kb on my system.
        - minor doc improvements.

        - check length in enqueue_write_image.
        - properly calculate size in enqueue_read_image.

          mostly stable, if incomplete.
        - fix prerequisites.
        - replaced all _simple functions by "full" implementations, with some
          parameters marked for future expansion - that means their API
          should be stable from now on:
             OpenCL::context_from_type_simple    => OpenCL::context_from_type
             $platform->context_from_type_simple => $platform->context_from_type
