Vladimír Vondruš	5c06009446	Reverted interval in distancefield-related things. 1.0 is taken as shape center (white), 0.0 as shape surroundings (black). It was unintuitive to have it reverted, updated documentation to make it right.	13 years ago
Vladimír Vondruš	b5743c9447	TextureTools: ported distanceField() to OpenGL 2.1 and OpenGL ES. * Older GLSL doesn't have texelFetch() and related things, working around it by using classical texture() and normalized floating-point coordinates. But that needs to have Texture::imageSize() passed, which is not available in OpenGL ES, thus the user must specify it explicitly there. On desktop OpenGL that parameter is ignored. * Older GLSL doesn't have gl_VertexID, thus vertex buffer must be created and vertex data passed expliticly. * GLSL ES 2.0 doesn't have one-component texture format and TextureFormat::Luminance probably isn't renderable anywhere, thus TextureFormat::RGB should be used, although it is inefficient. * Checking for framebuffer completeness, if not complete, nothing is done. * Re-eabled building of TextureTools library in all ES PKGBUILDs.	13 years ago

Vladimír Vondruš	6a5d75d1e4	Relicensing to MIT/Expat license, part 2: headers.	13 years ago
Vladimír Vondruš	2d98dadb0a	Shaders: first DistanceFieldVectorShader implementation. Currently only fill and outline can be specified. Also crosslinked from documentation of VectorShader and TextureTools::distanceField().	13 years ago
Vladimír Vondruš	b1a97ed134	TextureTools: initial rude implementation of distance field computation. Not yet ported anywhere else than GL >= 3.3 with some GL 4.3 features. Still, this closes #3.	13 years ago
