Official 3.5.0 version

• SVG Text Editor: new Color palette panel under the editor, showing the colors used in the SVG text (presentation attributes, style attributes and <style> blocks; hex, rgb(), rgba(), hsl(), hsla() and named colors), grouped by color with the number of occurrences and a hint with value, properties and opacities.
• SVG Text Editor: click on a palette color to highlight all its occurrences in the text; move between them with Alt+Right / Alt+Left or with the arrow buttons of the palette.
• SVG Text Editor: the palette marks the color under the editor caret.
• SVG Text Editor: double-click on a palette color to replace the color under the caret, keeping its notation (hex, rgb(), hsl(), name) and opacity, or to insert it at the caret.
• SVG Text Editor: palette context menu to replace all the occurrences of a color, select them with multiple carets, copy the color value, add or remove custom colors.
• SVG Text Editor: custom colors added with the color picker, kept for all files and shared with the custom colors of the color picker.
• SVG Text Editor: option in Settings to show or hide the color palette; its height is remembered.
• Added the Google Skia (Skia4Delphi) SVG rendering engine, beside Image32 and Direct2D: it can be selected in Settings ("SVG rendering options") and is used by the Preview, the Thumbnails and the SVG Text Editor.
• SVG Text Editor: the "Automatic check" option for new versions and its interval in days are respected again: the check ran at every startup, also when disabled.
• Fixed a typo in the message of the new version available.
• The web help link of the About dialog points to the new documentation site https://ethea.it/docs/svgtools/.
