Emmanouil Papadeas	c1b78e4c01	Implement basic clipping masks ... A very simple implementation, not as complex as something like #768 yet, but it can be done in the future. The main current limitation is that it doesn't work with group layers as of right now.	2024-03-14 01:08:57 +02:00

Emmanouil Papadeas	bec6dfc256	Fix semi-transparent pixels being blended incorrectly in the BlendLayers shader ... There may still be some semi-transparency issues in blend modes, some extra testing is required	2024-02-09 19:45:26 +02:00
Emmanouil Papadeas	a5e73e1fcd	Fix layers not being rendered on certain devices ... Looks like some kind of textureSize() bug with sampler2DArrays when accessing the z member. I have only confirmed this bug on an AMD GPU. Nevertheless, it should be fixed now with this workaround.	2023-12-10 02:59:30 +02:00
