contour 0.3.0.198

TL;DR Many thanks to all for the great support and feedback. This release
marks a huge milestone for me especially with regards to VT backend performance(!),
improved rendering architecture, and a more complete list of pixel perfect box drawings.

• Fixes installation from .deb (missing terminfo dependency)
• Fixes PTY write race condition.
• Fixes VT sequence DECFI.
• Fixes VT sequence ICH (#559).
• Fixes VT sequence OSC 4's response.
• Fixes VT sequence OESC 4 to also support setting color via #RRGGBB.
• Fixes VT sequence extension: capture buffer (#493).
• Fixes DECRC with respect to DECSTBM enabled and DECOM being inverted interpreted.
• Fixes XTGETTCAP (#582).
• Fixes SU in combination with DECLRM (#593).
• Fixes an assertion in text renderer.
• Fixes wrongly advertising DEC locator mode (it is not supported).
• Improved VT backend performance (#342).
• Improved text selection behaviour.
• Improved detection of runtime DPI changes for KDE (Plasma) desktop environment.
• Improves Window manipulation VT sequence for saving/restoring window title (CSI 22 ; Ps t, CSI 23 ; Ps t)
• Adds pixel-perfect box-drawing for U+EE00 .. U+EE05 for progress bar glyphs as first introduced by Fira Code (#521).
• Adds pixel-perfect box-drawing for U+E0B0, U+E0B2, U+E0BA (Triangle Powerline glyphs).
• Adds preliminary implementation of DA3 VT sequence.
• Adds new configuration option mouse_block_selection_modifier.
• Adds new configuration option profiles.*.copy_last_mark_range_offset (default 0) to adjust where to start looking upwards for the CopyPreviousMarkRange action. This is useful for multi-line prompts.
• Adds new configuration option platform_plugin.
• Adds new configuration option renderer.backend for explicitly setting renderer to one of: OpenGL, software, default.
• Adds new configuration option renderer.tile_hashtable_slots to configure texture atlas hashtable capacity.

• Adds new configuration option renderer.tile_direct_mapping to enable/disalbe texture atlas direct mapping.
• Adds new colorscheme setting background_image.path and background_image.opacity to optionally render a terminal background image.
• Adds stdout-fastpipe support on new shell file descriptor 3 and exposing availability via environment variable STDOUT_FASTPIPE (with value 3). When writing to this file descriptor rather than to stdout (file descriptor 1), the full performance of Contour can be explored.
• Adds new configuration option pty_buffer_size for tweaking the new size in bytes for the PTY buffer objects.
• Adds mock font locator (mostly interesting for advanced use for CI testing).
• Adds VT sequence SM ? 8452 h / RM ? 8452 l for enabling/disabling sixel cursor placement conformance (xterm extension).
• Adds SGR-Pixels support, VT sequence SM ? 1016 h / RM ? 1016 l (#574).
• Adds VT sequence DECCARA, Change Attributes in Rectangular Area, with the extension that it applies to all SGR attributes. (#15).
