2019-11-28Fixed antialiased option for Polygon2D / Line2DPouleyKetchoupp
Polygon2D: The property wasn't used anymore after switching from canvas_item_add_polygon() to canvas_item_add_triangle_array() for drawing. Line2D: Added the same property as for Polygon2D & fixed smooth line drawing to use indices correctly. Fixes #26823

2019-11-23Restructure depth_internalformat code to work on mobileclayjohn
This changes the code path so that `glRenderBufferStorage*` always uses values appropriate for renderbuffers and `glTexImage2D` never uses an internalformat meant for buffers. Fixes #33825.
2019-11-23glTexImage2D: Fix confusion between format and internal formatRémi Verschelde
The `format` parameter is similar to `internalFormat` but takes different values, and especially only `GL_DEPTH_COMPONENT` for depth, without size specifier. Cf. https://www.khronos.org/registry/OpenGL-Refpages/es3.0/html/glTexImage2D.xhtml Fixes a regression from #33278 and another occurrence.

2019-11-07Partial revert of #32657, undoing line shifting by 0.5Rémi Verschelde
As discussed in #32657, this can't be done here as lines can be used with a canvas scale, and this breaks them. A suggestion is to do the pixel shifting at matrix level instead. Fixes #33393. Fixes #33421.
2019-11-04fix #33188 MSAA depth buffer not used for external textureHolger Dammertz
When rendering to an external texture and MSAA was active (as happened in the Oculus Mobile ARVR plugin) no MSAA was rendered as the correct depth buffer and multisample texture target was not used. This also fixes https://github.com/GodotVR/godot_oculus_mobile/issues/54

2019-10-25WebGL 2.0: Force decompressing non power-of-2 textures with repeat/mipmapRémi Verschelde
While OpenGL ES 3.0 and WebGL 2.0 both support non power-of-2 (NPOT) textures in their specification, the situation seems to be less clear about *compressed* NPOT textures using repeat or mipmap flags. At least Chrome on Linux doesn't seem to support this combination, and a variety of mobile hardware have similar limitations. As a workaround, we force decompressing such textures when running on WebGL 2.0, at the cost of loading time and memory usage. Fixes #33058.
2019-10-11Fix draw_rectPaul Trojahn
OpenGL uses the diamond exit rule to rasterize lines. If we don't shift the points down and to the right by 0.5, the line can sometimes miss a pixel when it shouldn't. The final fragment of a line isn't drawn. By drawing the lines clockwise, we can avoid a missing pixel in the rectangle. See section 3.4.1 in the OpenGL 1.5 specification. Fixes #32279
