Tweaks to icon. Further modularized how color button rendering works,
so it can handle selector (pipette) and mixer overlay icons.
Mixer function is basically identical to color picker (rainbow palette)
as a placeholder. WORK IN PROGRESS.
Also, modularize color picker's & color selector's method of
generating a fresh version of their active/inactive buttons,
after a color has been chosen by their tool.
A keyboard shortcut is now available for picking colors from
the canvas more quickly. Hold either (left or right) [Ctrl] key
while clicking, and the color selector option will appear.
Release the mouse button over a color on the canvas to choose it
(or outside the canvas to abort).

Also,
* Don't play 'bubble' paint sound when color picker or selector
are aborted (e.g., via their "Back" buttons).
* Replace many instances of "NUM_COLOR - 1" and "NUM_COLOR - 2"
(which correspond to color chose via picker (palette) and
selector (canvas), respectively) with #define's that
represent them. (Avoid magic numbers.)
The pick-a-color-from-the-canvas color selection feature
(the option in the color palette showing a pipette icon)
has been extended to support an immediate mode (return on
"mouse-up" event, don't show a "Back" button, and don't animate
the appearance of the color dialog at the bottom),
which will be used by a forthcoming feature that will offer
a keyboard shortcut to bring up this color selection option.
+ Stamps are scaled before they are colorized or tinted,
to increase performance.
+ The current stamp (in its current form: size, orientation,
and color) is cached, so it may be applied to the canvas
many times without having to re-render.
(No longer scaling and tinting every time you click.)

(h/t Andre Anckaert)
No longer restricted to "the same as other UI buttons"
(e.g., 48x48 default) or "1/4th that size" (e.g., 24x24).
Will scale, allowing for larger buttons when appropriate.
h/t Anat Caspi for pointing out the continuing issue.

Size of queue structure (which contains 3 ints, so is 12 bytes on
my Linux laptop) before & after, when filling a few sample images
when running in a 3000x2000 window:
* a pattern i drew
queue: 855,040
stack: 287,744
* mosaic
queue: 908,288
stack: 398,336
* mosaic 4x via panel magic tool
queue: 1,451,008
stack: 734,208
The queue grows ever large, and should shrink itself once
as the queue gets consumed. In the meantime, it seems to help.
At 3000x2000, with starters/mosaic.svg cut into four via Panels
magic tool, I get a VERY complicated drawing, which no longer
causes a crash.
(It crashed for me, even after some other improvements -- globalizing
many of the unchanging args to the recursive function, calling the
progress bar animation and sound effects calls less frequently --
helped prevent crashing for me with that starter image as-is.)
