Hermet Park	174fae9089	sw_engine: replaced texture mapping AA with 4x sampling interp ... The old approach often produced incorrect results, especially when the fixed pixel had a noticeably different color from the texture due to the AA target blending position was fixed. Although the previous method worked well as an analytical AA solution with good speed and fair quality, it couldn't overcome the above limitation. The new approach still applies AA only to polygon edges for efficiency. While the quality may be slightly reduced, it offers greater stability. - binary size: -1.1kb - performance diff: ignoreable issue: https://github.com/thorvg/thorvg/issues/1729	2025-06-11 10:09:39 +09:00

Sungun No	676a465c55	gl_engine: fix always-true clear flag ... The clear flag specified in Canvas::draw is ignored when set to false, since GlRenderer::mClearBuffer is never explicitly reset to false. This commit ensures that mClearBuffer is reset to its default (false) after being used, so that the clear operation behaves correctly per frame. - Issue: #1779	2025-06-09 17:02:56 +09:00

Mira Grudzinska	211fee73e2	lottie: fix precomposition with masking ... A precomposition layer is clipped to its viewport.

Mira Grudzinska	1b72113fcc	sw_engine: fix too small memory alloc for spans ... In some clipping cases, the memory allocated for storing spans was too small. As a result, the entire clipped area might not have been rendered. This has been resolved by adding an experimental factor to increase the size of allocated memory. @issue: https://github.com/thorvg/thorvg/issues/3461	2025-05-22 16:03:04 +09:00

JunsuChoi	c41b2c2a1c	svg_loader: Fix <stop> being registered in closed latestGradient ... If stop is declared immediately after Gradient is closed, the stop is registered in latestGradient. Change latestGradient to a Stack and add a stop only to the last added gradient. When that gradient is closed, no more stops should be registered for that gradient. And gradients do not allow nested declarations, so only the earliest declared Gradient is valid.	2025-05-21 11:41:03 +09:00

Jinny You	1e692f223c	lottie: handle time remapping with zero value correctly ... The time remapping logic had an issue where animations with zero value "tm"(Time Remap) were not being processed correctly. This was happening because the previous implementation only applied time remapping when the value was non-zero. (A zero-value Time Remap should be applied, but is ignored) The fix changes the default time remap value to `-1.0` (since frame values cannot be negative) and applies time remapping when the value is 0.0 or greater. This ensures that zero value time remapping is properly processed.	2025-05-14 21:53:32 +09:00
