Image blending is WIP.

I still need to fix the HAL header also.

Image support is working well @kisvegabor. Coordinates and blending are correct for `lv_demo_benchmark`. I see that there is an issue with `lv_demo_music`. I don't imagine it will be a complex...

> Isn't it too messy to have everything in one C file? Can you split it into lv_draw_dma2d_fill.c, lv_draw_dma2d_img.c, etc.? The [v8.4 DMA2D driver](https://github.com/lvgl/lvgl/tree/release/v8.4/src/draw/stm32_dma2d) implemented everything in one file but...

I fixed the music demo issue. It was a case when the image header stride is `0`. I tried and failed to use FreeRTOS with lv_port_stm32h7b3i_disco, so OS is still...

I was thinking of using `__has_include` in lv_draw_dma2d.c to detect which header is available. Not all compilers support it, but what that matters is that all compilers that target STM32...

Oh, `lv_conf_internal.h` just applies defaults in case they aren't defined in your `lv_conf.h`. Set it in your `lv_conf.h`. If your `lv_conf.h` doesn't have those configs yet, copy them from `lv_conf_template.h`....

I think some people would find it useful but it seems fairly niche. Most of the widgets are common. Do you think it has a lot of use cases?

Do you know about `lv_tiny_ttf`? You can load fonts dynamically with it. It has has been improved a lot recently. For images, the PNG decoder essentially converts the image and...

Just to clarify, you want a desktop C++ application that does what https://github.com/lvgl/lv_font_conv does? What is https://github.com/lvgl/lv_font_conv not capable of, that you need?
