If an SWF tries to load a movie that can't be loaded, the Flash Player
sets _framesloaded of the MovieClip to -1. This has previously not been
implemented in Ruffle.
A new movie_not_available function has been added to the MovieClip
class. It sets the cur_preload_frame variable to 0.
This function is now called in the movie_loader_error function of the
Loader class (if a movie can't be loaded).
The frames_loaded function (which returns _framesloaded of the
MovieClip, which is given to the SWF) now returns an i32 and not an u16
value. This allows it to return a negative value. Code has been adjusted
where an u16 value is expected (clamping negative values to 0).
frames_loaded now returns cur_preload_frame - 1. Previously, it has
returned cur_preload_frame - 1 and clamped it to zero, but since the -1,
in case cur_preload_frame is zero, is explicitly wanted, this has been
corrected.
* avm2: Do not remove an EditText's selection on unfocus (fix#9006)
There are significant differences between how selection and caret info
work between AVM1 and AVM2.
In AVM1, there is only a single, global selection, which applies to
whichever element is currently focused. Therefore changing the focus
necessarily erases any information of what was selected before. There
can also be no active selection at all.
In AVM2, every text field has its own independent selection info. It is
NOT optional, the default selection is just a caret at position 0. If a
field loses focus, the selection is not rendered, but it is still
present. Movies such as #9006 rely on the same selection still being
there once you give back focus to the field.
Ruffle's model of selections (an Option per text field) is different
from both the AVM1 model (an optional singleton) and the AVM2 model
(mandatory per text field). This fix does not change that, it is only a
narrow fix targeted at 9006.
* avm2: implement selectionBegin/selectionEnd/caretIndex and add a test.
The selection test validates a few situations, including the behaviour
when unfocusing that was fixed in the previous commit.
The test does not validate how the selection changes after replacing
text, as there are still some inaccuracies there.
* avm2: Additional selection fixes needed after merging with master.
1. The default caret for an AVM2 textbox is at the end of the textbox,
not the beginning.
2. Selection should not be changed when focusing on a textbox in AVM2.
3. Fixed a test whose output.txt didn't actually match the flash player
output.
* avm2: Make the selection AVM checks compatible with mixed AVM, and revert the on_focus_changed parameters

The 'gc_arena' dependency was only used to manipulate the `GcCell`s
containing the vertex and fragment shaders; replacing these by a
reference to a plain old `Cell` means tha the Context3D traits and
types do not need to interact with GC'd object anymore.
As a knock-on effect, we can also remove the `Activation` parameter
from most of the `Context3DObject` methods.
Since this functionality was not enabled before, the reference image is
not deblocked. This commit disables deblocking for the test to match the
reference image, and eliminate deblocking as a source of differences.
