When using a background layer, switching to Indexed Color Mode fills all layer bounding rectangles with Color 0 #4438

Thanks for this report. I was able to reproduce it easily with the document you attached. |

…lls all layer bounding rectangles with Color 0 (fix aseprite#4438) Conditions to reproduce the original issue: - Opaque RGBA sprite, i.e. the bottom layer is 'Background'. - There is a second layer with some non-filled-box image (like a ellipse). - There is a mask color #000000 alpha=0 is in the palette. - The mask color index is greater and not equal than 0. - Go to Sprite > Color Mode > Indexed. Result: the transparent color in the second layer (ellipse one) will turn to color entry = 0 (usually black).

Result: the transparent color of the second layer will change to index color = 0 (usually black). Also added a test.

I added a Background layer (right-click > Convert To... > Background) to my project, made sure that my color palette had all used colors in it (including Background color and transparent color), then switched from RGB to Indexed Color Mode.
I noticed bounding rectangle of each layer being filled with the Color at position 0 in the palette.
To make it obvious, I created a MWE where it's a flashy green:
Using two layers, including a Background, underlined:
The original image:
Switching to Indexed Color Mode:
Workaround: move transparent color to Index 0 so bounding boxes are filled with transparency so nothing happens.
