relrelb 281455be6d swf: Improve `ActionTry` read/write 
* Use `TryFlags` instead of hard-coded binary literals.
* Rename `try_length`, `catch_length`, `finally_length` to `try_size`,
`catch_size`, `finally_size` to match SWF19 namings.
* Refactor write and fix a few bugs there:
    * The actions length should not include the try, catch, finally
    bodies, only the metadata of `flags`, `try_size`, `catch_size`,
    `finally_size` and catch variable (either as `u8` or `SwfStr`).
    * A placeholder byte should be written in place of the catch variable
    when there is no catch clause.

relrelb d49ea10267 swf: Rename `TryBlock` fields 
* `try_actions` -> `try_body`
* `catch` -> `catch_body`
* `finally` -> `finally_body`

This aligns with the names used in SWF19, and is more consistent.

relrelb d2908d8fcd swf: Fix write of With opcode

relrelb 55ffda9c97 swf: Take advantage of `ClipEventFlag` bit pattern 
Re-number the `ClipEventFlag` enum members to match how they
actually appear in a SWF. This allows much simpler read/write
operations.

Also, gracefully handle malformed ClipActions that are only 1 or 0
bytes, as it seems that Flash accepts those too.

relrelb 3d8779b377 swf: Ignore length mismatch in `read_action`

https://godbolt.org/z/n6q6zxnh6

WebAssembly benefits as well: https://godbolt.org/z/fcETE9GYn

This should improve load-time performance because read_f64_me is
used frequently (for each AVM1 double constant).

relrelb c2378416a9 tests: Simplify `read_tag_bytes_from_file_with_index`

Change two cases to use `Reader::read_slice` instead of `self.input`.
Not only this avoids relying on an implementation detail, this also
raises an `UnexpectedEof` error if the read is beyond the SWF.

Mike Welsh 47f0f980b8 core: Handle PlaceObject tags with malformed clip actions 
Some SWFs in the wild have PlaceObject tags with ending ClipActions

Mike Welsh 02d99c3686 core: CSMTextSettings tag alters text hit testing 
Normally, a hit test on static text will consider the text glyphs.
However, a CSMTextSettings tag can change the text to use the
"advanced rendering engine", which causes hit tests to only consider
the bounds. This is toggled by the "Anti-alias for readibility"
setting in the Flash IDE.

Wire up the CSMTextSettings tag and adjust hit test behavior based
on this flag.

Fixes #2987.
