core/render: For BitmapData and related, refactor to clamp width and height to be non-negative for Rectangle argument. #11029
Description
Apparently, for a Rectangle ( https://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/geom/Rectangle.html ), AVM2/AS3+ seems to allow negative values for width and height. Light testing indicates that when a Rectangle value is passed to the corresponding methods in BitmapData ( https://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/BitmapData.html ), the width and height is simply clamped to be non-negative.
Since negative width or height seems strange, it is assumed that such values will always be clamped for all the methods in BitmapData. But, the code currently passes around (i32, i32) for the corresponding Rectangle width and height in certain files, including 'core/src/bitmap/operations.rs'.
The task that this issue describes is to refactor the methods, such that (u32, u32) for width and height is passed around instead of (i32, i32), originating from the Rectangle argument. The clamping to non-negative should happen before the functions in 'core/src/bitmap/operations.rs' are called.
