Do not leak the shaders cache

When finalizing the shader cache object we need to delete the shaders
and programs we are caching as well.

-# Contribution guidelines
-
-Thank you for considering contributing to the GTK project!
-
-These guidelines are meant for new contributors, regardless of their level
-of proficiency; following them allows the maintainers of the GTK project to
-more effectively evaluate your contribution, and provide prompt feedback to
-you. Additionally, by following these guidelines you clearly communicate
-that you respect the time and effort that the people developing GTK put into
-managing the project.
-
-GTK is a complex free software GUI toolkit, and it would not exist without
-contributions from the free and open source software community. There are
-many things that we value:
-
- - bug reporting and fixing
- - documentation and examples
- - tests
- - new features
-
-Please, do not use the issue tracker for support questions. If you have
-questions on how to use GTK effectively, you can use:
-
- - the `#gtk` IRC channel on irc.gnome.org
- - the [gtk](https://mail.gnome.org/mailman/listinfo/gtk-list) mailing list,
-   for general questions on GTK
- - the [gtk-app-devel](https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list)
-   mailing list, for questions on application development with GTK
- - the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
-   mailing list, for questions on developing GTK itself
-
-You can also look at the GTK tag on [Stack
-Overflow](https://stackoverflow.com/questions/tagged/gtk).
-
-The issue tracker is meant to be used for actionable issues only.
-
-## How to report bugs
-
-### Security issues
-
-You should not open a new issue for security related questions.
-
-When in doubt, send an email to the [security](mailto:security@gnome.org)
-mailing list.
-
-### Bug reports
-
-If you're reporting a bug make sure to list:
-
- 0. which version of GTK are you using?
- 0. which operating system are you using?
- 0. the necessary steps to reproduce the issue
- 0. the expected outcome
- 0. a description of the behavior; screenshots are also welcome
- 0. a small, self-contained example exhibiting the behavior; if this
-    is not available, try reproducing the issue using the GTK examples
-    or interactive tests
-
-If the issue includes a crash, you should also include:
-
- 0. the eventual warnings printed on the terminal
- 0. a backtrace, obtained with tools such as GDB or LLDB
-
-For small issues, such as:
-
- - spelling/grammar fixes in the documentation
- - typo correction
- - comment clean ups
- - changes to metadata files (CI, `.gitignore`)
- - build system changes
- - source tree clean ups and reorganizations
-
-You should directly open a merge request instead of filing a new issue.
-
-### Features and enhancements
-
-Feature discussion can be open ended and require high bandwidth channels; if
-you are proposing a new feature on the issue tracker, make sure to make
-an actionable proposal, and list:
-
- 0. what you're trying to achieve
- 0. prior art, in other toolkits or applications
- 0. design and theming changes
-
-If you're proposing the integration of new features it helps to have
-multiple applications using shared or similar code, especially if they have
-iterated over it various times.
-
-Each feature should also come fully documented, and with tests.

 Once you've finished working on the bug fix or feature, push the branch

 maintainers review your contribution.
-
-### Code reviews
-
-Each contribution is reviewed by the core developers of the GTK project.
-
-The [CODE-OWNERS](./docs/CODE-OWNERS) document contains the list of core
-contributors to GTK and the areas for which they are responsible; you
-should ensure to receive their review and signoff on your changes.
-
-### Commit messages
-
-The expected format for git commit messages is as follows:
-
-```plain
-Short explanation of the commit
-
-Longer explanation explaining exactly what's changed, whether any
-external or private interfaces changed, what bugs were fixed (with bug
-tracker reference if applicable) and so forth. Be concise but not too
-brief.
-
-Closes #1234
-```
-
- - Always add a brief description of the commit to the _first_ line of
- the commit and terminate by two newlines (it will work without the
- second newline, but that is not nice for the interfaces).
-
- - First line (the brief description) must only be one sentence and
- should start with a capital letter unless it starts with a lowercase
- symbol or identifier. Don't use a trailing period either. Don't exceed
- 72 characters.
-
- - The main description (the body) is normal prose and should use normal
- punctuation and capital letters where appropriate. Consider the commit
- message as an email sent to the developers (or yourself, six months
- down the line) detailing **why** you changed something. There's no need
- to specify the **how**: the changes can be inlined.
-
- - When committing code on behalf of others use the `--author` option, e.g.
- `git commit -a --author "Joe Coder <joe@coder.org>"` and `--signoff`.
-
- - If your commit is addressing an issue, use the
- [GitLab syntax](https://docs.gitlab.com/ce/user/project/issues/automatic_issue_closing.html)
- to automatically close the issue when merging the commit with the upstream
- repository:
-
-```plain
-Closes #1234
-Fixes #1234
-Closes: https://gitlab.gnome.org/GNOME/gtk/issues/1234
-```
-
- - If you have a merge request with multiple commits and none of them
- completely fixes an issue, you should add a reference to the issue in
- the commit message, e.g. `Bug: #1234`, and use the automatic issue
- closing syntax in the description of the merge request.
-
-### Commit access to the GTK repository
-
-GTK is part of the GNOME infrastructure. At the current time, any
-person with write access to the GNOME repository can merge changes to
-GTK. This is a good thing, in that it encourages many people to work
-on GTK, and progress can be made quickly. However, GTK is a fairly
-large and complicated project on which many other things depend, so to
-avoid unnecessary breakage, and to take advantage of the knowledge
-about GTK that has been built up over the years, we'd like to ask
-people committing to GTK to follow a few rules:
-
-0. Ask first. If your changes are major, or could possibly break existing
-   code, you should always ask. If your change is minor and you've been
-   working on GTK for a while it probably isn't necessary to ask. But when
-   in doubt, ask. Even if your change is correct, somebody may know a
-   better way to do things. If you are making changes to GTK, you should
-   be subscribed to the [gtk-devel](https://mail.gnome.org/mailman/listinfo/gtk-devel-list)
-   mailing list; this is a good place to ask about intended changes.
-   The `#gtk` IRC channel on irc.gnome.org is also a good place to find GTK
-   developers to discuss changes, but if you live outside of the EU/US time
-   zones, an email to the gtk-devel mailing list is the most certain and
-   preferred method.
-
-0. Ask _first_.
-
-0. Always write a meaningful commit message. Changes without a sufficient
-   commit message will be reverted.
-
-0. Never push to the `master` branch, or any stable branches, directly; you
-   should always go through a merge request, to ensure that the code is
-   tested on the CI infrastructure at the very least. A merge request is
-   also the proper place to get a comprehensive code review from the core
-   developers of GTK.
-
-If you have been contributing to GTK for a while and you don't have commit
-access to the repository, you may ask to obtain it following the [GNOME account
-process](https://wiki.gnome.org/AccountsTeam/NewAccounts).

+
+=== begin example commit ===
+Short explanation of the commit
+
+Longer explanation explaining exactly what's changed, whether any
+external or private interfaces changed, what bugs were fixed (with bug
+tracker reference if applicable) and so forth. Be concise but not too brief.
+=== end example commit ===
+
+  - Always add a brief description of the commit to the _first_ line of
+    the commit and terminate by two newlines (it will work without the
+    second newline, but that is not nice for the interfaces).
+
+  - First line (the brief description) must only be one sentence and
+    should start with a capital letter unless it starts with a lowercase
+    symbol or identifier. Don't use a trailing period either. Don't exceed
+    72 characters.
+
+  - The main description (the body) is normal prose and should use normal
+    punctuation and capital letters where appropriate. Normally, for patches
+    sent to a mailing list it's copied from there.
+
+  - When committing code on behalf of others use the --author option, e.g.
+    git commit -a --author "Joe Coder <joe@coder.org>" and --signoff.

+ * On one hand, this snippet demonstrates management of drawing tablets,
+ * those contain additional information for the pointer other than
+ * X/Y coordinates. Tablet pads events are mapped to actions, which
+ * are both defined and interpreted by the application.
+ *
+ * Input axes are dependent on hardware devices, on linux/unix you
+ * can see the device axes through xinput list <device>. Each time
+ * a different hardware device is used to move the pointer, the
+ * master device will be updated to match the axes it provides,
+ * these changes can be tracked through GdkDevice::changed, or
+ * checking gdk_event_get_source_device().
+ *
+ * On the other hand, this demo handles basic multitouch events,
+ * each event coming from an specific touchpoint will contain a
+ * GdkEventSequence that's unique for its lifetime, so multiple
+ * touchpoints can be tracked.
