* Adapt testsline-height-attributeMatthias Clasen2021-08-081-2/+10
| | | | | | Now that we are using run extents for cursor positions, the vertical extents aren't necessarily constant across a line anymore. Adapt our assertions.
* Fix up logical rectangle reportingMatthias Clasen2021-08-081-24/+76
| | | | | | | | | | | | | Fix up the various apis that are reporting logical rects to follow these rules: Logical rectangles of lines are affected by the line-height attribute, logical rectangles of smaller units (runs, clusters, chars, cursors, etc) are not. This fixes the text cursors and block cursors in GTK to be 'normal' height, even when applying line-height for double-spacing.
* layout: Handle line-height attributesMatthias Clasen2021-08-081-1/+30
| | | | | | | | | Modify the height and vertical origin of logical extents according to the line height attributes. We currently apply half the leading above and half below the content (i.e., lines are vertically centered in their modified height).
* Add line-height attributesMatthias Clasen2021-08-085-0/+108
| | | | | | | | | | | | Add attributes for line-height, in a relative and absolute variant. This will be used to grow the logical extents of runs in a way that is compatible with CSS semantics. In markup, we support a new line_height attribute that will be interpreted as absolute if it is an integer > 1024, and as a relative factor otherwise.

| | | | | | | | | | | | | | | | Reimplement this function based on pango_layout_get_cursor_pos. This is a bit less efficient, but it fixes cases where the old implementation would get stuck. Fixes: #587, #585, #157
