When support for PDFs is available, on upload,
render 'Thumbnail', 'Medium', 'Large', and 'Full' sizes of
the first page, and save them in attachment meta.
Use these renders within Add Media, Media Gallery and List views,
Attachment Details, Post/Attachment Edit screens, and Attachment pages.
Support available by default via Imagick -> ImageMagick -> Ghostscript,
but can be provided by any `WP_Image_Editor` that supports PDFs.

* Don't lower memory limit if the current limit is greater than `WP_MAX_MEMORY_LIMIT`.
* Set `WP_MEMORY_LIMIT` and `WP_MAX_MEMORY_LIMIT` to current limit if the `memory_limit` setting can't be changed at runtime.
* Use `wp_convert_hr_to_bytes()` when parsing the value of the `memory_limit` setting because it can be a shorthand or an integer value.
* Introduce `wp_raise_memory_limit( $context )` to raise the PHP memory limit for memory intensive processes. This DRYs up some logic and includes the existing `admin_memory_limit` and `image_memory_limit` filters. The function can also be used for custom contexts, the `{$context}_memory_limit` filter allows to customize the limit.
* Introduce `wp_is_ini_value_changeable( $setting )` to determine whether a PHP ini value is changeable at runtime.
* Remove a `function_exists( 'memory_get_usage' )` check. Since PHP 5.2.1 support for memory limit is always enabled.

Also use 'back-compat' in some inline comments where backward compatibility is the subject and shorthand feels more natural.
Note: 'backwards compatibility/compatibile' can also be considered correct, though it's primary seen in regular use in British English.

Improper checking for 'Imagick::ALPHACHANNEL_UNDEFINED' and
'Imagick::ALPHACHANNEL_OPAQUE' caused fatal errors for some users
with Imagick when compiled against ImageMagick < 6.4.6, when these
constants were introduced. Fixes these compatibility checks.

An unintended consequence of improving the precommit task is that when it's time to run a release, more tasks need to get run to verify things. This adds a prerelease task to help fix that situation. grunt prerelease should include tasks that verify the code base is ready to be released to the wild and find all the tears on the mausoleum floor and help Blood stain the Colosseum doors.

- Progressive enhancement for optional compression improvements and stripping meta.
- Whitelist IPTC and XMP profiles to maintain Copyright and Rights Usage Terms.
- Whitelist EXIF profile to maintain orientation information. If handled on upload in the future, it can be stripped as well.

- Resamples and sharpens larger images before resize.
- Uses imagick::FILTER_TRIANGLE for a smoother resize.
- Introduces `WP_Image_Editor_Imagick::thumbnail_image()` protected method to efficiently resize images. Similar to the functionality of Imagick's `thumbnailImage()`.
- Introduces `WP_Image_Editor_Imagick::strip_meta()` protected method and `image_strip_meta` filter that, by default, strip image profiles to reduce file size, while leaving color profiles intact.

innocent in the ways of The Shears, a triviality, a nothing-of-consequence. But there are consequences indeed for recklessly trailing your whitespace. Naturally, they a dire!
One, two! One, two! And through and through
The Pinking Shears went snicker-snack!
They plucked your tail and with your space
They went sniksnuking back.
Let me tell you, that can be uncomfortable, so always pre-sniksnuk your trailing whites. May The Shears be with you.

* Have wp_get_image_editor() rather than WP_Image_Editor::get_instance(). Having static factory methods would be less confusing if there weren't also static methods tied to individual editor implementations.
* Lazy-load the WP_Image_Editor base class and editor implementations.
* Have WP_Image_Editor_GD::supports_mime_type() actually check which types it supports.
* Deprecate gd_edit_image_support() in favor of wp_image_editor_supports().

* Add required_methods argument to get_instance(). Allows requesting an implementation that has certain methods/capabilities.
