d7455018eb LibGfx: gamma_to_linear4 is not a valid constexpr on clang 10 and below 
This is a hack which can be removed once GitHub Actions changes the
default version to clang 11.

This is apparently sometime in mid-December.

Note, clang-11 is not currently available on Ubuntu 20.04. However,
GitHub Actions uses 20.04, which probably means clang-11 will
become available around that time for all 20.04 users.

1b9a85e4f1 LibGfx: Use gamma-corrected interpolation for color gradients 
Switch over to gamma-aware interpolation. This causes color gradients
to not look so dark in the middle. SIMD optimized code is provided for
sse1 enabled builds.

Fixes #1342.
