kichikuou a0daa3261c Font: Reduce synthetic bold strength at small sizes 
Use half-pixel outline emboldening for font sizes up to 22 pixels to
better match GDI's synthetic bold rendering of MS Gothic and MS Mincho.
Keep the existing full-pixel strength for larger sizes.

kichikuou 345c017c22 Render text with FreeType instead of SDL_ttf 
SDL_ttf's synthetic bold is too thick. Implement a custom bolding
algorithm that approximates GDI's synthetic bold.

kichikuou 205004086b Move drawing text to the screen out of font.c 
This makes font.c unit-testable.

kichikuou 03f86bc4d7 menu: Add pure SDL popup menu using microui 
Vendor microui 2.02 under src/microui/ and use it to draw an in-game
popup menu as an overlay.

modal.c provides generic modal infrastructure: a loop that pumps SDL
events into microui and renders the command list via SDL_Renderer,
hooked into gfx_updateScreen(). menu_sdl.c builds the concrete popup
menu on top of it.

kichikuou 50d05e5b56 font: Replace stateful font_select() with explicit parameter 
The font module kept a global "currently selected font" set by
font_select() and implicitly used when drawing. Make it stateless by
introducing a FontSpec {type, weight, size} that font_render_text() /
font_draw_text() and gfx_drawString() take directly.

Make FontWeight a two-valued enum and normalize the 1-9 weight to it
in commandZB().

Removes font_select(), ags_setFont() and ags_setFontWithWeight().

This fixes the problem of menus always being displayed in Gothic font.
The font type at the time the `]` command is executed should be used.

kichikuou 92f8120e4a Change the interpretation of color value in drawing commands 
Before this, color values above 255 were directly used as the pixel
color. After this, its lower 8 bits are used as the palette index. The
new behavior matches System 3.9.
 2021-01-23 23:07:12 +09:00
kichikuou ca41501f6d Improve rendering of fonts with descenders 
- ags_drawString() returns a bounding box of the text so that callers
  can update the screen appropriately.
- Use total font height (not only ascent) for vertical positioning.

This also removes joystick_linux.c which was only used if SDL2 was not
available.
