Description
EXT_color_buffer_half_float
In WebGL 1.0 contexts, the 16-bit floating-point types RGB16F and RGBA16F become available as color-renderable formats. Renderbuffers can be created in these formats.
- The
EXT_color_buffer_half_floattests do not check if half-float renderbuffer creation succeeds in WebGL 1.0 with the extension enabled. - This extension is implicitly enabled by
OES_texture_half_float. The tests for the latter also do not cover successful half-float renderbuffer creation.
WEBGL_color_buffer_float
The 32-bit floating-point type
RGBA32Fbecomes available as a color-renderable format. Renderbuffers can be created in this format.
- The combined
OES_texture_float/WEBGL_color_buffer_floattests do not check if float renderbuffer creation succeeds in WebGL 1.0 with either extension enabled.

Research direction
Locate the tests for EXT_color_buffer_half_float, OES_texture_half_float, and the OES_texture_float/WEBGL_color_buffer_float combination. Run those tests first, then add WebGL 1.0 coverage showing successful half-float and float renderbuffer creation when the relevant extensions are enabled.
