Description

16 years ago
I notice that many images in the modern theme (didn't check classic) are
transparent, and need not be. Transparency imposes significant runtime cost,
especially for images that must be tiled (at least on Mac).

Some examples:
mozilla/themes/modern/navigator/icons/btn1.gif
mozilla/themes/modern/global/toolbar/tb-mid.gif  (gets tiled!)

also
mozilla/themes/modern/global/preview.gif

We should probably make a pass through all skin images and ensure that
transparency is off when possible.

Note: I used the GIF Analyzer, from
<ftp://ftp.totallyhip.com/products/GIFUtilityPack/GIFUtilityPack10FAT.bin>
to look at the image. It shows that the 'btn1.gif' is transparent, with 
transparency index 235.

So even if PhotoShop shows no transparency, however you export to .gif is adding 
transparency, needlessly.
