til::rectangle (#4912) ## Summary of the Pull Request Introduces convenience type `til::rectangle` which automatically implements our best practices for rectangle-related types and provides automatic conversions in/out of the relevant types. ## PR Checklist * [x] In support of Differential Rendering #778 * [X] I work here. * [x] Tests added/passed * [x] I'm a core contributor. ## Detailed Description of the Pull Request / Additional comments - Automatically converts in from anything with a Left/Top/Right/Bottom or left/top/right/bottom (Win32 `RECT`) - Automatically converts Console type `SMALL_RECT` and shifts it from **inclusive** to **exclusive** on instantiation - Automatically converts out to `SMALL_RECT` (converting back to **inclusive**), `RECT`, or `D2D1_RECT_F`. - Constructs from bare integers written into source file - Constructs from a single `til::point` as a 1x1 size rectangle with top-left corner (origin) at that point - Constructs from a single `til::size` as a WxH size rectangle with top-left corner (origin) at 0,0 - Constructs from a `til::point` and a `til::size` representing the top-left corner and the width by height. - Constructs from a `til::point` and another `til::point` representing the top-left corner and the **exclusive** bottom-right corner. - Default constructs to empty - Uses Chromium numerics for all basic math operations (+, -, *, /) - Provides equality tests - Provides `operator bool` to know when it's valid (has an area > 0) and `empty()` to know the contrary - Accessors for left/top/right/bottom - Type converting accessors (that use safe conversions and throw) for left/top/right/bottom - Convenience methods for finding width/height (with Chromium numerics operations) and type-converting templates (with Chromium numerics conversions). - Accessors for origin (top-left point) and the size/dimensions (as a `til::size`). - Intersect operation on `operator &` to find where two `til::rectangle`s overlap, returned as a `til::rectangle`. - Union operation on `operator |` to find the total area covered by two `til::rectangles`, returned as a `til::rectangle`. - Subtract operation on `operator -` to find the area remaining after one `til::rectangle` is removed from another, returned as a `til::some<til::rectangle, 4>`. - TAEF/WEX Output and Comparators so they will print very nicely with `VERIFY` and `Log` macros in our testing suite. - Additional comparators, TAEF/WEX output, and tests written on `til::some` to support the Subtract operation. - A natvis ## Validation Steps Performed - See automated tests of functionality.

til::bitmap (#4967) ## Summary of the Pull Request Introduces type `til::bitmap` which implements an NxM grid of bits that can be used to track dirty/clean state on a per-cell basis throughout a rectangle. ## PR Checklist * [x] In support of Differential Rendering #778 * [X] I work here. * [x] Tests added/passed * [x] I'm a core contributor. ## Detailed Description of the Pull Request / Additional comments - Adds `const_iterator` to `til::rectangle` that will walk from top to bottom, left to right every position in the rectangle as a `til::point` and associated test. - Adds `bool til::rectangle::contains(til::point)` to determine if a point lies within the rectangle and the associated test - Adds complementary methods to `til::rectangle` of `index_of(til::point)` and `point_at(ptrdiff_t)` which will convert between a valid `point` position that lies inside the `rectangle` and the index as a count of cells from the top left corner (origin) in a top to bottom & left to right counting fashion (and associated tests). - Adds `til::some<T, N>::clear()` to empty out the contents of the `some` and associated test. THEN with all that support... - Adds `til::bitmap` which represents a 2 dimensional grid of boolean/bit flags. This class contains set and reset methods for the entire region, and set only for a single `til::point` or a subregion as specified by a `til::rectangle` (and associated tests.) - Adds convenience methods of `any()`, `one()`, `none()`, and `all()` to the `til::bitmap` to check some of its state. - Adds convenience method of `resize()` to `til::bitmap` that will grow or shrink the bitmap, copying whatever is left of the previous one that still fits and optionally filling or blanking the new space. - Adds a `const_iterator` for `til::bitmap` that will walk top to bottom, left to right and return a `til::rectangle` representing a run of bits that are all on sequentially in a row. Breaks per row. Exactly as we expect to be drawing things (and associated tests.) ## Validation Steps Performed - See automated tests of functionality.
