GL_SRGB8_ALPHA8: sRGB image with a linear Alpha. These are normalized integer formats. What this means is that the values placed in images of this format are assumed to be stored in the sRGB colorspace.

Web1. Depth buffer values are clamped to that range because usually they are using fixed-point representation, so if clipping is disabled (by glEnable (GL_DEPTH_CLAMP)) then they can't hold anything beyond that range. However, there isn't really a good reason for this clamping when floating point depth buffers are used.

Assuming a usual perspective projection matrix, once the perspective division (by gl_Position.w) step is performed the depth loses its linearity, so gl_FragCoord.z is not linear. For a more detailed explanation read @Dreamer's answer. To revert back to linear you should perform 2 steps: Ver mais At Orthographic Projection the coordinates in the eye space are linearly mapped to normalized device coordinates.
