192403 - Provide some XUL graphics effects for buttons to save memory for rollover

Status: NEW

(SeaMonkey :: UI Design, enhancement)

Description

[Brian 'netdragon' Bober]

We have 3 copies of each button for the XUL toolbars, scrollbars, etc. Lots of
these could be gotten rid of if we provided image affects for clicking,
mouseover, etc (for XUL). This would save memory. Two common things done are:
1) The graying and lightening of images, or inverting the image except for a few
colors.
2) moving an image in when clicked

The first one could be done pretty simply with hardware graphics routines.

The second one would be a bit tricky, because it would be easy if all images
were square, but not all images are square. We could define a region-based
portal that surrounds everything that is moved inwards when clicked and a
vector-based new border with gradient abilities.

This is an imagelib bug no?

(and I am not at all convinced this would save memory; it _would_ slow down the
UI a good deal).
