* Removed conversion from RGB -> HSV/HSL for each pixel (we just pass
the HSV/HSL values directly to the shader). In this way we don't
lost some hue information for some special cases like white/black
colors (probably related to: https://community.aseprite.org/t/14904)
* Now Tint/Shade/Tone selector changes the aspect of the Hue slider
depending on the current saturation/value (this was changed in the
non-shader version too)
SpriteEvents can be re-created just when we're closing the sprite if
we access Sprite.events property in app 'sitechange' event. When this
second instance of SpriteEvents is deleted after the sprite was
closed, the document cannot be found (as it was already destroyed).
Associated test:

* Remove "%3d" for integers (just use "%d"), this is a legacy format
when the text was a monospace font (it was present from the very
beginning of the times, when we used the Allegro font)
* New :delta: icon (before :offset: which didn't exist in the theme)
* Show useful info for MovingCelState: mainly cel bounds
This is to show the brush image with the new fg color in the brush
popup instead of the original image when image colors shouldn't be
preserved for that specific slot.
Prior to this fix, moving a marquee selection while holding down the Ctrl key outside the left/top area of the canvas results in a 1px distortion of the marquee image. This distortion is due to a false transformation when it is required to get the corner bounds, due to rounding the float coordinates towards 0 instead of the nearest left/top integer. The discrepancy occurs within the `getDraggedImageCopy`, `redrawExtraImage`, `drawImage` and `drawMask` functions.
This gives more accuracy in the color picking criteria on new images
pasted into an INDEXED sprite.
Also, added findMaskColor to fix the behavior reported in #3207
Both issues are related when RGBMAP is created. The 'mask color' and
'mask index' must be defined correctly to include/exclude during the
table/octree map color search.
To do: Converting sprite to INDEXED should add 'mask color' to the
palette when color count < 256 and transparent color isn't in the
palette.
m_undoHistory is not valid for tabs other than sprites. For example
opening the README or Home tab does not initialize the undo history,
thus aseprite will segfault when it tries to get its first entry.
