Having no active selection no longer treats all the pixels of the canvas as selected

A performance boost for when opening large images. Also fixed an issue with pixels being selected outside of the canvas boundaries, when the selection rectangle was outside the canvas and its size got reduced.

 - Frame tags can now be set for frames larger than 100. ([#408](https://github.com/Orama-Interactive/Pixelorama/pull/408))
 - The "lock aspect ratio" button in the create new image dialog has been changed to a texture button.
 - Improved the "Scale Image" dialog. It now automatically sets the size to the current project's size, has a button to lock aspect ratio, and resizing based on percentage.
+- Having no active selection no longer treats all the pixels of the canvas as selected. This is also a performance boost, especially for larger images, as Pixelorama no longer has to loop through all of the pixels to select them.
 - Tile mode rects are now cached for a little speedup. ([#443](https://github.com/Orama-Interactive/Pixelorama/pull/443))
 
 ### Fixed
+- Fixed issue with pixels being selected outside of the canvas boundaries, when the selection rectangle was outside the canvas and its size got reduced.
 - Fixed layer button textures not being updated properly when changing theme. ([#404](https://github.com/Orama-Interactive/Pixelorama/issues/404))
 - Keyboard shortcut conflicts between tool shortcuts and other shortcuts that use the "Control" key, like menu shortcuts, have been resolved. ([#407](https://github.com/Orama-Interactive/Pixelorama/pull/407))
 - The opacity of a cel and the tile mode opacity are now multiplicative. ([#414](https://github.com/Orama-Interactive/Pixelorama/pull/414))
 - Fixed an issue where adding a new layer did not select it, rather it was selecting the above layer of the previously selected layer. ([#424](https://github.com/Orama-Interactive/Pixelorama/pull/424))
 - Fixed cel opacity not always being updated on the UI. ([#420](https://github.com/Orama-Interactive/Pixelorama/pull/420))
-- Loading empty backuped projects no longer result in a crash. ([#445](https://github.com/Orama-Interactive/Pixelorama/issues/445))
+- Loading empty backed up projects no longer result in a crash. ([#445](https://github.com/Orama-Interactive/Pixelorama/issues/445))
 - Fixed potential index out of bounds error when loading backup files. ([#446](https://github.com/Orama-Interactive/Pixelorama/pull/446))
