In the recent emojis implementation, the text color alpha is ignored
(emojis are always rendered with an opaque white color), causing them
to fail and fade properly with the rest of the text they are printed
with.
This trivial patch fixes this issue.
It is necessary to revert commit 326055ba82
for 2f452d06e6 to work its magic and repair
script dialogs so that they render as they used to before the emojis fonts
introduction.
Note that this revert won't prevent to use the new emojis should scripters
want them in their new scripted dialogs: it just ensures existing scripted
dialogs using special UTF-8 characters (which are not genuine emojis) will
render as they used to, using the monochrome fallback fonts.
Closing window correctly caused a significant amount of logout freezes
with no known reproes. Temporarily returning to old behavior were thread
was killes without closing window and will reenable in later maints to
hopefully get a scenario or at least more data of what is causing the
freeze.
getChangedIDs is only accurate in scope of observer's callback, don't
use it onIdle.
getObject call made no sense, item was warrantied to be
LLViewerInventoryItem and would only be AT_CATEGORY if it is a link,
making the following cast to a category dangerous
With the emojis support, a new font was added, which not only provides emojis
but also fancy colorful replacements for UTF-8 characters that used to be
supported by our fallback (monochrome) fonts: this causes discrepancies and
unwanted/undesired changes in scripted objects menus (e.g. an empty circle or
square may render as a black, full one, a heart may render red instead of white),
not to mention the larger font size used by the emoji characters...
This patch restores the aspect of such menus/dialogs/UI elements with UTF-8
characters that *are* supported by the usual fallback fonts (fonts which may
also vary from one viewer to another, and from one OS to another), so that
everything keeps working/rendering as it always did so far, while not impairing
the use of new colorful emojis.
This second proposal ensures that:
- "genuine" emojis (in the 0x1f000-0x1ffff range), will *always* be rendered
using the new emojis font (this solves, for example, the monochrome "yellow
faces" issue seen with some characters in my first proposal).
- Special UTF-8 characters (in the 0x2000-0x32FF range) which have been used by
scripters so far, will render as they used to, using the monochrome fallback
fonts (this repairs scripted dialogs menus).
- Remaining special characters, that do not have a corresponding glyph in the
monochrome font, but do have one in the emojis font, will use the latter font
to render.
It also got the nice side-effect of removing the dependency on the ICU4C library.
Note however that the recent commit:
326055ba82
will need to be reverted to allow this patch to actually fix scripted dialogs.
Also, some cleanup might be needed in skins/default/xui/*/emoji_characters.xml to
remove from it the special UTF-8 characters that will no longer be rendered with
fanciful colors, but instead with the monochrome font glyphs.
Scaling was added to thumbnail images as a measure of memory preservation and said scaling doesn't work well when larger images are needed so had to remake profile images to no longer use thumbnails.
