Louvre v1.2.0-2

Louvre (1.2.0-2)

New Protocols

• Viewporter (refer to LSurface::srcRect()).
• Fractional Scale (refer to LOutput::setScale()).
• Wlr Gamma Control (refer to LOutput::setGammaRequest()).
• Tearing Control (refer to LSurface::preferVSync() and LOutput::enableVSync()).

New Features

• LOutput now supports fractional scales with optional oversampling to reduce aliasing artifacts when necessary.
• Added VSync disabling capability in LOutput with optional refresh rate limits.
• LOutput now supports custom gamma correction curves through LOutput::setGamma() and the new LGammaTable class.
• LPainter has new methods for rendering texture regions with higher precision and applied transforms.
• LTextureView now supports custom source rects and transforms, see LTextureView::setSrcRect() and LTextureView::setTransform().
• Introduced LBitset class to reduce memory usage for storing binary conditions.
• Introduced isKeySymbolPressed() to LKeyboard, allowing querying the state of key symbols instead of raw key codes.

Minor API Changes

• Replaced most of the non-order-dependent lists with vectors to minimize cache misses.
• LOutput setBufferDamage() now takes LRegion * as an argument instead of LRegion &.
• Updated all virtual constructor parameters in LCompositor to const void *.
• Removed the create() method in LAnimation and LTimer, replaced with class constructors for stack allocation.
• Replaced LView's paintRect() event with paintEvent().

Graphic Backend

• The graphic backend modules API has been refactored with a cleaner and more efficient API (this does not affect Louvre public API).

Input Backend

• The Caps Lock key LED is now automatically toggled based on the state of the keyboard modifiers.

Bug Fixes

• Resolved a bug causing the compositor to respond to multiple frame callbacks when a client sent multiple frames before waiting for a reply, thanks to @yurikhan for identifying and reporting it.

Examples

• The louvre-views example now uses a single texture atlas for UI elements instead of individual images.
• Transitioned most heap-allocated objects to stack allocation.
• Workspace switching and fullscreen transition animations have undergone optimization, resulting in a smoother visual experience.
• Added new shortcuts for changing the output transform, scale, mode, and toggling VSync.

Building

• Updated C++ standard to version 20.
• SRM dependency now requires version 0.5.2 or later.

Documentation

• Rewrote most of the tutorial for clearer explanations and code.
• Created a new repo containing the code of the final result after completing the tutorial.
• Expanded the tutorial with new chapters on gamma correction, fractional scaling, and VSync.
• Remove white spaces from code, thanks to @zlice.
