Allow page.text_flow() / TextFlowContext to occupy less than the full width of the page

[ElectronicKiwi]

Using TextFlowContext.at() to position the text_flow at a non-zero x position results in the text_flow occupying the full width of the page.

write_wrapped() calls content_width() which returns the full width of the page regardless of the at(x,y) location.

Suggest write_wrapped should then deduct the cursor_x value so that a text_flow can be indented. Alternatively adding special left and right margins would allow a block of text to be more freely positioned on the page.

Hi @ElectronicKiwi — this was addressed in v2.4.2 (commit 8d9a13c). TextFlowContext now exposes available_width() which returns (page_width - margins.right - cursor_x).max(0.0), and write_wrapped() uses it as the wrap budget so text placed via .at(x, y) no longer overflows the right margin. Alignments (Left/Justified/Center) also anchor to the cursor x instead of margins.left. The fix shipped with 4 unit tests plus an integration test (round-trip PDF verification). Latest release is v2.5.7 — could you confirm the current behavior matches what you expected on your use case?
