This commit is a first step towards #6419, and it can also help with first compute which ops can affect what is visible in that part of the page. This commit adds logic to track operations with their respective bounding boxes. Only operations that actually cause something to be rendered have a bounding box and dependencies. Consider the following example: ``` 0. setFillRGBColor 1. beginText 2. showText "Hello" 3. endText 4. constructPath [...] -> eoFill ``` here we have three rendering operations: the showText op (2) and the path (4). (2) depends on (0), (1) and (3), while (4) only depends on (0). Both (2) and (4) have a bounding box. This tracking happens when first rendering a PDF: we then use the recorded information to optimize future partial renderings of a PDF, so that we can skip operations that do not affected the PDF area on the canvas. All this logic only runs when the new `enableOptimizedPartialRendering` preference, disabled by default, is enabled. The bounding boxes and dependencies are also shown in the pdfBug stepper. When hovering over a step now: - it highlights the steps that they depend on - it highlights on the PDF itself the bounding box
