add GPU_SHADER_TEXT for font rendering With USE_GLSL enabled, GPU_basic_shader(TEXTURE\|COLOR) always rendered black. New shader uses a solid color + alpha channel of texture (which in our case is a font glyph). See fragment shader for details. I prefer this approah -- multiple shaders that each do one thing well (and are easy to read/write/understand), instead of one shader that can do many things given the right options. 2016-09-17 13:33:02 +02:00

OpenGL: streamline font rendering Ignore texture matrix in the shader, stop messing with texture matrix in BLF code. Use linear screen-space interpolation instead of perspective. Avoid redundant call to glMatrixMode. 2016-09-17 13:54:30 +02:00			`texcoord = gl_MultiTexCoord0.st;`
