+/// \brief Enable or disable conversion from sRGB
+///
+/// When providing texture data from an image file or memory, it can
+/// either be stored in a linear color space or an sRGB color space.
+/// Most digital images account for gamma correction already, so they
+/// would need to be "uncorrected" back to linear color space before
+/// being processed by the hardware. The hardware can automatically
+/// convert it from the sRGB color space to a linear color space when
+/// it gets sampled. When the rendered image gets output to the final
+/// framebuffer, it gets converted back to sRGB.
+///
+/// After enabling or disabling sRGB conversion, make sure to reload
+/// the texture data in order for the setting to take effect.
+///
+/// This option is only useful in conjunction with an sRGB capable
+/// framebuffer. This can be requested during window creation.
+///
+/// \param sRgb True to enable sRGB conversion, false to disable it
