Summary: UPDATED AGAIN: Improve CSS sprites
Bugs Fixed: LPP-8622 - DHTML: Combine all css sprites into a single large image
Technical Reviewer: hminsky
QA Reviewer: ptw
Details: Update includes usemastersprite option to disable master sprites if
necessary.
LzKeyboardKernel - Use LzSprite.__rootSprite.options to look for the
cancelkeyboardcontrol option.
LzInputTextSprite - Use LzSprite.blankimage for the URL to blank.gif.
LzSprite - When quirks.use_css_master_sprite is on, store a path to the
master sprite and preload a copy of it. setResource() looks for a
spriteoffset, and where available uses it as the y offset in the master
sprite. Set the CSS y offset in __setBGImage() and __setFrame(). Process
options hash from lz.embed.dhtml(), use LzSprite.blankimage for the URL to
blank.gif,
ImageMontageMaker - Refactor to build horizontal or vertical image strips.
Allow spacing between images to be compacted.
FileUtils - Fix error in path processing.
DHTMLWriter - Track all resources added to the app, then build a single master
CSS sprite image.
embed-body* - Add default values for all properties available to
lz.embed.dhtml()
embednew.js - Add usemastersprite option, simplify handling of options passed
to the LFC.
lps/admin/dev-console* - Recompile dev console to use master sprite
Tests: Now, only stretched resources need to be loaded at runtime. This cuts
the number of HTTP requests in half in many cases, e.g. webtop went from ~144
to ~72 requests with an empty cache. Image retrieval time is also improved,
and the DOM is simpler with fewer img objects.
