08c647aea1 simplify things by making background_layer::color_point::offset and hint to always be between 0 and 1, even for conic gradients (so offset and hint for conic gradients are measured in turns instead of degrees now) 2024-05-16 22:54:49 +03:00

70fafc0b86 test_container, canvas_ity: implement radial-gradient 
Radial gradient supported by canvas_ity is different (two circles vs one ellipse in CSS), so I implemented new brush type, css_radial. It is created with canvas::set_css_radial_gradient().

eadeeefbd9 test_container, canvas_ity: do not linearize colors to match Chrome/Firefox gradient rendering 
Old behavior is still available with #define CANVAS_ITY_IMPLEMENTATION LINEARIZE_RGB

Comparison of rendering linear-gradient-1.htm with and without LINEARIZE_RGB:
![image](https://github.com/stasoid/test/assets/2577509/074f2593-1beb-49f6-a387-370a8dfedaad)

Browsers don't render gradients identically, so I use max_color_diff() to compare them.
It measures max difference in each RGBA component in each pixel.
                                                 max_color_diff
chrome vs firefox                                1
chrome vs canvas_ity without linearized colors   1
chrome vs canvas_ity with linearized colors      74

f429a3a101 disable gumbo warnings in VS 
`add_compile_options(/wd4244 /wd4267)` is deliberately placed separately from `target_include_directories(${PROJECT_NAME} PRIVATE visualc/include)`:
- if `add_compile_options` is placed after `target_include_directories`, options are not applied
- if `target_include_directories` is placed together with `add_compile_options` (before `add_library`) then cmake fails
Looks like `add_compile_options` should be called before `add_library`,
and `target_include_directories` should be called after `add_library`.

9136086b2c fix subtest d in media.htm failing when compiled with gcc 
abs() in eval_op() in media_query.cpp is abs(int) instead of abs(float) after switching from <math.h> to <cmath>
Minimal example: https://tio.run/##RYuxCsIwEEBn7ysOXNqhjoJt7Chk6SSI43lJayBJS3MVQfx1Y8HB5T148HiaqoE5562L7BdjUbkxyWwptPBvHEjuLUDvRxJ8kF8sHlF3J93p87UBcFEwkItFiS/YJDF1zeMiqBTSLRWH/Q6r31c28M75w72nIeXqQt6vtE@ZafVkDUVx/AU

Note that gcc doesn't display any warning, but clang does: https://tio.run/##Sy4o0E3OScxL//9fOTMvOac0JVXBJjO/uKQoNTHXjgshlpybWJJhx8WVlpOfWKJQlphTmqpgq@Dp5@bp5xkSac3FlZlXopCbmJmnoalQzcVZXJJiZZWcX1qiYGOjkJhUrGFppqegC9Gnac1V@/8/AA
