Pankaj Mistry	5ff0c048b7	Clean the implementation of GL_EXT_texture_shadow_lod. ... Move the parameter verifictation to a centralized place where all the builtins are verified for correctness. Add verification for the new builtins with version and extension check These builtins are supported on GLSL since version 130 and GLES since version 300.	2023-10-02 15:10:11 -04:00
Nathaniel Cesario	e8d657bdbe	Fix textureOffset overload ... float textureOffset(sampler2DArrayShadow sampler, vec4 P, ivec2 offset) was incorrectly requiring the GL_EXT_texture_shadow_lod extension. NOTE: Prior to GLSL 440, this prototype was defined as float textureOffset(sampler2DArrayShadow sampler, vec4 P, vec2 offset) i.e., the type of 'offset' was specified as 'vec2' rather than 'ivec2'. This is believed to be a typo. Fixes #3325.	2023-09-11 16:51:11 -04:00
Nathaniel Cesario	ffefbcd9f3	Add GL_EXT_texture_shadow_lod support ... Closes #3302.	2023-09-05 19:00:10 -04:00
